NEW! Lyman Case Trim Express: Unboxing, Overview, Brass Trimming

[@lymanproductsanalytics8467]

Hi Gavin- Liz from Lyman Products here. You can also mount the trimmer perpendicular to the front of your bench so you are pushing down to trim each case instead of sideways for an even more comfortable motion. This was suggested by another reloader at SHOT Show.

[@Ultimatereloader]

Awesome- will try that- good to hear from you Liz!

@@gerrymatheson4020 I think in your lap. But a short plastic bowl, with a hole centered in its bottom, that fits over the collar's threaded bace should minimize the mess. Think of a Brass Confetti Catching Saucer. HaHa I'd put a Long Think into this before trying it out.......

[@MikeMcCasland27]

A quick comment to the folks talking about the varying trim lengths; those aren't a result of this case trimmer being "inaccurate". Any case trimmer that uses the case shoulder to index (such as the Giraud, WFT, Frankford Arsenal, Lyman etc.) will only cut as accurately as your shoulder bump. You'll notice in the video he's getting varying trim lengths on the .308 batches; this is most likely a result of him using mixed headstamp brass, unannealed brass that has a mixed number of firings; or his sizing die is setup to 'over bump' the shoulder beyond what is required, and you're seeing the varying springback in the brass. Regardless, it's not an issue with the trimmer. The adjustment on where the trimmer indexes never changes/moves. You can think of any 'shoulder indexing' case trimmer as effectively the same thing as a trimming headspace comparator. Any deviation in the brass is going to show up in your trim lenghts. As a result, to get an accurate trim (within .001 across ~100 cases), the rest of your process needs to be wire tight (same headstamp, annealing each firing, dies setup properly). That said, having a few thousandths (.001-.005) difference in brass length is not going to affect your groups at all, at any range, or any discipline.

[@Sshooter444]

The Anal-Squad likes perfection!

[@lanceschul]

I agree about the shoulder variances. That’s why I prefer an LE Wilson for any precision work.

[@ab0ad]

SuperDutyTX: I agree. I will take a " SHOULDER INDEXED TRIMMED case " over an "overall case trimmed case " ANY DAY. Reason why. Your neck length WILL be more consistent with a "shoulder indexed". Funny how some will worry about the overall case length, and then be INCONSISTENT in their "neck chamfer depth", thus changing neck length. BEST way for the "Anal-Squad" would be a shoulder with an cutter that a least cuts the chamfer too at the same time it trims. If some one can show me different I am willing to learn.

Exactly...

[@RogueBlackheart]

This is what I was leaning towards, but I cant find a three way cutter in .25 caliber, any ideas?

So does the Giraud Tri Way Trimmer and is faster then using a drill press.

[@seanwinner9924]

Thank you for your support and knowledge. You have knon idea how important and helpful you are to our community. I’m just starting out reloading. The first(and hope only)reload I purchased is the Dillon XL750. It’s quite a complex setup. I’m 56 and have been a gun enthusiast all my adult life. After building my own AR15/AR10 rifles I thought 6.5 Grendel is quite expensive not to mention 450BM/308/300blk/223/9mm and so on. It seemed to be my next step towards enjoying my hobby more. I can’t wait to shoot 6.5 Grendel in the rifle I built with ammo I made. Pretty excited about it. Oh and I purchased the Lyman and don’t remember what I did with the instructions. I thought no worries I’ll just go to my local reloading expert and see. Again thank you so very much. Sean Winner

[@davecollins2097]

I'm wondering that the variable length such as Super Duty is describing, may create an issue with crimping, .005 is a lot, could require sorting cases and crimp adjustments to make it consistent, for those who have a need to do it. Setting the crimp on a short case could cause issues on the long ones. Something to consider at least.

[@dieseldog6824]

He was .007" difference in 3 cases .... terrible imo

[@bliksemdonder5624]

Use a collet crimp and absolute case length no longer matters.

[@whogivesacrap84]

Love this trimmer. I just wish they had a similar form factor deburring and pocket cleaning station

[@kdglock4491]

I noticed the primers were still intact. How did you know the true size if you didnt resize first?

[@davep1808]

Good catch. I saw that one too !

[@gerrymatheson4020]

I thought he said they were resized...he read it off the box of .308... so apparently resized and reprimed...

[@4499duke]

Thanks for the reviews on this and other equipment. I think I heard you say to trim then rotate the brass 180 degrees and trim again to make sure it's square. If the first trim isn't square, rotating the brass 180 and trimming again will not make it square, it will make the next shaped like a tubular spearhead. Sloped so slightly you can't see it, bu tit will not be square. If the machine doesn't trim square on the initial insertion, it is defective

[@rjinnh3933]

The 180deg rotation gives you a second chance at proper shell case alignment relative to the cutting head. Same when precision seating bullets. Your comment is pertinent if we assume perfect case alignment, which isn't possible given the vendor supplied case alignment colletts. A 180deg twist is a minor addition to the overall case prep process, as it is with precision bullit seating, both of which are considered, 'Good Reloading Practices'......

[@kre4tur3]

Only 2 things i wish lyman would change about the unit. Add detents to the adjustment wheel so it locks and is adjustable in half thousandths for the detents, and offer an optional 3-way cutter head like the RCBS 3-way cutter

[@godswatcher]

Seems like fairly accurate machine The problem is after you trim them all the length you have to take time to debut the inside and the outside of the case mouth and neck. That takes a lot of extra time. I use RCBS trimmer with a 3 way cutter system after the case trim the length is automatically Debured on the inside and the outside.

[@100reality2]

I was just thinking the same thing.i have a Lee 3 way trimmer I think I'll just stick with it because as you say using this machine you are just adding another process.

[@michaelt.9372]

I cannot for the life of me get consistent trims. Twisting, pushing lightly, pushing hard, everything. Nothing would get me consistent trims. Switched to the RT1500 and it worked great. The huge price difference sucks but so much more consistent and I’m very happy.

[@Malukevin407]

What about chamfer and deburing?

[@tr-zz8fz]

Yes it looks good but you still have to debur and chamfer and from what i see it will only do bottle neck cases so i will stay with my old Hornady trimer and power drill

[@russdennis7026]

Noob question. Should I resize de prime first?

[@andyprairiedog]

Yes, you should resize/deprime first, trim accordingly, chamfer/deburr. I thought I saw GT's .223 casings were still primed as he was trimming them. Possibly to only demonstrate the trimming process. I may be wrong on his particular process...GT may resize, trim, deprime and onto the next task. Reloaders have their ways and it is very interesting to see how we all do our brass preparations. Me, I resize/deprime at the same time, trim (if needed on high volume shooting...definitely on my match ammo), deburr/chamfer and onto next task.

[@larrydesantis9800]

Its really all about what you're welling to pay. The Lyman does an adequate job of trimming for $150, But the Giraud and Henderson trimers are the ultimate. They deburr and champher at the same time. Henderson $778 and the Giraud around $495. But by the time you add cutters and holders/collets , they even out around $900.for say four different calibers. But they are sweet

[@steverowe2943]

If I did not already have several WFTs and the Girard trimmer, I would opt for this as it seems to be a good value. I would probably mount this on a block of wood to get it to sit higher for comfort as having my hands in a tray full of brass shavings is not comfortable. I suggest using PUG17 (or similar) gloves to give a better grip on the base and protect hands. As a timesaver, I suggest twisting the brass while in contact with the cutter to make it square in lieu of pulling it out turning and re-inserting.

[@TargetTime]

Why over the giraud? I don't have the motor unit but the triway.. But both have trim, chamfer, and deburing. After using this you'd still have to do 2 more passes on a separate device

[@gerrymatheson4020]

I have no issues holding onto them, even with a little Unique lube left on them or my fingers from resizing. Because it's spring loaded you control the pressure and can ease it into the cutter. I mostly just push on the base with my thumb and don't even really "hold on to" the case head... I agree with you about truing up the trim by turning the case...kind of. I just ease up the pressure, turn it a bit, press it again, repeat a couple times til nothing touches the cutter...

[@GunnerMan1812]

have you created a trimmer comparison lineup? or have you considered doing one?

[@lerb33]

After trimming, should I chamfer / deburr ?

[@FullSendPrecision]

I've always purchased 3 way trimmers because they're worth the money to me. But I've seen some of these universal type trimmers be VERY hard to get repeatable and consistent results from. This one looks like a winner! - But if you only shoot a few calibers, the Giraud Tri Way Trimmer is a REAL winner of a tool at 105 bucks or so

[@xc75ranger]

Agreed! You "get's what you pay for". The only downside, for the Giraud gets a little expensive for each caliber. I started using the Hornady (hand) case trimmer, then bought Lee individual trimmers, and also tried the Lyman EZ Trim set trimmers. Then tried the WFT's in 308 and 223, which weren't too bad, but they didn't chamfer and deburr. I finally spent the money and purchased the Giraud power case trimmer, in 2 calibers. Never been happier, I also purchased a Geraud Tri Way Trimmer in 308, for times when I didn't want to reset the power trimmer from 223 to 308. I bought the Lyman on sale from Midway for $114, for the other misc. calibers I load, on a not too regular basis.

[@jw3256]

Hi Gavin thanks for the review, However, how does the Lyman compare to your earlier reviews of the L.E. Wilson case trimmer with the micrometer and slow speed drill attachment you reviewed. BTW I always enjoy your video however I get confused as which you recommend since you seem to review something new every week. Therefore which I would buy is always a toss-up when comparing similar tools with all the reviews you have published. In addition, I will be waiting to hear your final recommendation for Single Stage press reviews you have mentioned in a shoot out.

[@drfroglegs]

I see it doesn't chamfer/debuff like a Giraud. Honestly, I prefer not to chamfer/deburr on the trimmer. I've noticed when I wet tumble after I chamfer/deburr (when I use my giruad) it files down the sharp edge and changes the OAL of the case. I prefer a flat cut, wet tumble, then chamfer after the cases dry (no need to deburr if you wet tumble). Looks like an awesome product!

[@drfroglegs]

FYI, to get around the issue with the Giraud I can only trim the cases after I have wet tumbled them.

[@k.w5804]

@@drfroglegs You can adjust the amount of deburring and chamferring right? My 223 cutter came installed and set with very aggressive chamferring. It goes so deep and case neck could almost cut my finger. I adjusted the cutter angle a little bit to get it to deburr and chamfer the way I wanted.

[@drfroglegs]

@@k.w5804 the cutter is in a V shape. You can adjust it so there is less of an angle on the chamfer, but doing so will add more of an angle on the deburr (and visa versa). To my knowledge there is no way to cut without a chamfer and deburr due to the V shape of the cutter.

[@k.w5804]

@@drfroglegs True it's always less of one and more of the other. I haven't used Giraud for a long time. I have actually grown to like my Dillon rt1500 and its squre cut, which was what I disliked in the first place to get the Giraud lol. I use M die to just touch the case neck then tumble and load away. If I feel fancy, I will use hand tool to debur and chamfer. For both 223 and 308, I couldn't tell any difference in accuracy be it trimmed by Giraud or Dillon. They are all sub-moa ammo if I do my part.

[@lyfandeth]

Couldn't the same tool slso chamfer the case mouth at the ssme time, if they shaped the tooling for it? (Lyman, that'll cost you you a 10% commission if you do it.)

[@rsf5898]

That would require either a cutter head which has to be adjusted for each calibre (i.e. basic neck diameter) or interchangeable calibre specific fixed cutter heads - both solutions are already in use by other manufacturers so perhaps no commission from Lyman for you this time.

[@davep1808]

I bought one of these and am glad i did. I like to resize my brass first before i trim them though.

[@gerrymatheson4020]

?? Of course...that's the correct way to do it...and I believe that is what he was demonstrating...

[@gerrymatheson4020]

Ps...I love mine... The case trim Xpress combined with the case prep Xpress make a great pair!

[@varanidguy]

This reminds me a lot of the trimmer built into the Frankford Arsenal case prep center.

[@Goinghot]

Frankford arsenal does this same operation and more. These type machines work off referencing the shoulder of the case. Therefore if you're very consistent when you resize, you'll get consistent overall length when you trim.

[@timfarley6493]

Does the Lyman trimmer chamfer and deburr the case mouth???

[@curtsantner6023]

I have been using the Lee case trimmer that I need to attach to a power drill and after about fifty pieces, my fingers are sore. I hate case trimming but this looks like an easy way to accomplish this task.

I just ordered one these after trimming 1500 rounds of .223 with the same 3-jaw Lee trimmer, it took me the better part of 12 hours to get through them all. My fingers felt like they were about to fall off lol. It gives really accurate and consistent results but the wear and tear to your digits is just plain old unacceptable.

I wonder if you could ditch the spring- and insert a washer in its place same thickness as the spring when compressed??

[@Jiminico]

I ditched the spring altogether soon after starting a big batch of 223. No washer or anything. Ran fine, actually better, easier and faster. I got sick of fighting the increasing tension as the case was getting closer to indexing on the shoulder. Unless I jammed it in there with force every time I wouldn’t get consistent trim length from shoulder to mouth. Sometimes I over did it and made some lines around the datum line because it’s difficult to get a good feel when you have the right amount of pressure. And by having to press harder it’s easier to get uneven cuts because of the inherent slop in the unit. No spring and now consistent and more even cuts. Just pay attention to push it in straight in line every time. I wear a thin rubber coated work glove and just jam it home and it goes fast.

[@GetMeThere1]

Seems a contradiction for the trimmer to headspace on the shoulder while you measure from the case head.

[@rjinnh3933]

Properly sized Once Fired Brass Trimmed using the Shoulder as a reference will result in Case Head to Trimmed Neck measurements being consistent from case to case. If the Base/Neck measurements are inconsistent, then the Trimming itself was inconsistent. The more consistent the case prep process, the more consistent the Head to Trimmed Neck measurement. BTW: The SAAMI spec for 223 Head to Neck is 1.760 +0.000 -0.030 or 1.730Min to 1.760Max.

[@garrytalley8009]

Sizing on the shoulder does create inconsistent length unless they are all new same lot or manufacturer or been shot out of the same rifle. If they are not all the same if you crimp the crimp could vary. Looks like it would be fast way to do bullets for the same rifle under those circumstances. Personally I do one at a time with inexpensive Lee Trimmer by hand. Length is always the same. Easy enough to do just watching television. I use a light crimp on all my rounds and I know they are the same length with the Lee Trimmer. If one is going to trim off the shoulder and only have one caliber there are better options. I do own an older Lyman Power Trimmer that just sits because it doesn't even square the cut. It's alignment is off. It does look like this new one would be squared but it most likely costs more than it's worth. A Lil Crow caliber specific would be a better way to go if one was only doing one to a few calibers. Lyman makes some good stuff, but they make their share of not so good stuff too.

[@marlinhadicke7958]

No one has asked if the trimmer chamfers inside or out while it's cutting. Does it ?

[@gerrymatheson4020]

Not really...because it measures from the shoulder... but turning the case does potentially true up the trim. If by chance one side is a little longer (not perfectly square) turning it 180 and pushing it in again will even out the longer side (and will not touch the shorter side) thereby squaring or truing it up...

[@bluescatreimer]

I used mine for the first time yesterday for 30-06 brass. I couldn't believe how easy it was to adjust and use. Now I don't dread trimming rifle brass. Now they need to come up with some kind of adapter for straight walled brass.

[@andicerocks]

The only way I see a straight case being trimmed in such a way would be with a bearing perfectly sized to the inner casing that free floats as you insert the case to be trimmed. Maybe just a blank or slug would work as well with the outer edge slotted so it could cut the case only after being properly resized. Just a thought.

It starts spinning fine, but after few seconds it slows down and it start making squeaking noise. If I try to trim a case, the motor jams and dents the case. Originally I thought I just needed a new blade, so I ordered one from Lyman website. However, this did not fix the problem. Now I am back trimming my brass using Redding 2400 manual trimmer. When the XPress was working, I was very happy with it. I quickly figured out how to trim within 0.002" all my brass. When the motor started to slow down, I noticed that I had to trim the same case twice to reach my target brass length without changing the size setting wheel (trim, pull back case and then insert it again and trim). Hopefully, Lyman will fix the issue or send me another unit. As a said, when this machine works, it does a great job and it is super easy to use. Luckily, I only shoot 6.5CM and 308Win and both of my rifles are custom chambered for specific bullet grains, so I have only to trim once in a while. My Lapua 6.5CM brass has been reloaded 7 or 8 cycles and the cased grew only 0.002" to 0.003", so I think I will shoot out the barrel before I need to trim the 6.5CM brass. My 308Win grows about 0.002" after a reloading cycle, so I just need to trim 308Win about every 3 or 4 cycles. I do FL sizing and I clean (sonicate) my brass twice. First time I clean the brass using JB Paste to make the neck area perfectly shiny and clean (carbon gunk on a case, especially neck and shoulder area can negatively affect sizing) and then I sonicate for 60min using Lyman detergent. Afterwards I dry my cases (I use warm air blast and swabs), I size them and do case prep (I wait for primer pocket to get dry since it is much easier to clean primer pocket when the pocket is dry than wet). At the end I sonicate prepared case for another 60 minutes using the same Lyman solution I was using for the first wash cycle. At the end, my Lapua brass looks new and super clean inside (I inspect every case with flash light). I do about 10 washing cycles with the same Lyman sonicating solution (I mix 1:40 in lab grade deionized water). Over two years of reloading, one lesson that I learned is that you save money by buying high-end reloading tools and brass. After I tried Lapua brass, I do not use anything else. It is one of the best investments that a reloader can make and in a long run it saves you money as you do not have to buy new brass for a long time.

Well ok then Bogg, I've had mine for about a year. I like the fact I dont have to hook up the drill to my 'ol bannaza case lathe when I want to trim. The fittings are easyer then the allen wrench s to set up the machine. Still have to champer inside and out side . I wish the machine had more functions like the rcbs, lyman, frankford, ect work stations. Trim time is less then my old machine. I size my cases before I trim anyway , so nothing new there. in all, I like the maching for the price.

[@curtsantner6023]

Do you use this trimmer before or after resizing the cases?

[@poyo503]

After resizing

[@BobbyOfEarth]

After being fired, the shoulders need to be bumped back, so, one should always expect non-uniform case lengths when trimming cases that have not already been resized to SAAMI specs.

[@EdSigman]

This is a very good presentation as are all of your discussions that you provide to us. I would like to suggest that when you evaluate a (new product) that a comparison be made to another product of the same function in order to benchmark the results of the new product. Of all your products, you may have the opinion of a "favorite" and why for comparison to the new product evaluations.

[@ryc3rz]

Dissapointed. I haven't heard of this before and I was hoping it would be an alternative to a dillon press mounted trimmer. Maybe someone will make adapters later on to mount it onto Dillon X650?

[@angelscomputers]

that trimmer also chamfer and debur? Can do 300BLK? Im comparing it with my Frankford which is 3 different steps and is not easy for 300BLK

[@lonewanderer3603]

Yes it will do 300blk but you'll have to chamfer and debur in a separate step.

[@gerrymatheson4020]

It does such a clean smooth cut you could almost skip chamfer and deburring...but easy enough to do... and no problem doing .300blk... I've been converting a whole bunch... works great...easy to set up, easy to adjust...

[@nagyrezk6682]

Great videos, may I know the model and specs of your Lathe and your drill machine ( I am a QC engineer with German engineering degree ) thanks

[@charlesrhea6810]

This trimmer looks good,I want to try it for sure. If you any trimmer that indexes on the shoulder there is going to be variation in the trim length especially when cases are inconsistent ( different brands ,case thickness, fired vs new) . Iran into the same problem with "the little crow" trimming .308 cases.

[@charlesrhea6810]

C Rhea-sorry about that-using the Crow I went through almost an entire bin of new Lapua brass , and few old ones before discovering that many were cut too short-most not bad but some were even more than.005 more than desired. Therefore,I don't uses this until on new/unfixed brass or on brass before it's been resized (and shoulder set at uniform length/or fire formed in the same rifle that you are going to us. Otherwise you may want to use the older methods initially.

[@williebulletman5217]

Thank you Gavin and early Merry Christmas

[@jasonb4350]

You trimmed 223 that was not sized and I believe you had a mix of 308 , this explains the extreme range of measurements. If you had fully resized brass your measurements would be much closer and a better example for the people watching.

[@Jmastffp]

Of the two (the Lyman and the Frankfort Arsenal) which case trimmer do you prefer?

[@gerrymatheson4020]

I prefer this one (Lyman Xpress)...quieter, smoother, very user friendly, no issues holding on to short cases like .300blk...

[@15TNar]

Cool video, thanks for sharing as that makes life easier for any volume shooter

[@zacharylawrence839]

Do you trim your brass casing before you size them and tumble them?

[@gerrymatheson4020]

Always resize and then trim...

[@thiagoordine1270]

Will it work for pistol caliber? I need trim .38 Super Auto brass...

[@gerrymatheson4020]

No, shouldered cases only...

[@blindsey1076]

What is that machine labeled pm-949v?

[@Ultimatereloader]

It's a Bridgeport-style milling machine! Lots of videos coming. Here's the product page: www.precisionmatthews.com/shop/pm-949ts-tv/ mine is the variable speed head model...

[@mikecrotsley6962]

Precision Matthews PM-949V milling machine

[@repairfreak]

Thats his hopped up kitchen-aid batter mixer for when he builds cakes. 😂

[@alzathoth]

IMO they should have color coded the bushings to different calibers. looks like a great tool tho.

[@xc75ranger]

Where did you get the case for storing the extra bushings?

[@gerrymatheson4020]

It all comes with it...

[@gerrymatheson4020]

I love mine. Very user friendly...
