Truing a CZ457 Action For Better Accuracy🎯

[@parischristner8799]

This is what separates you from other gun smiths, you are not satisfied resting on your reputation. You are always looking for new ways to improve your craft. Keep up the outstanding work Kenny. Thank you for all your hard work and your outstanding videos.

[@sjohnson1776]

I truly enjoy your videos because I learn something every time I watch one. That 5 shot bug hole was brilliant! Thanks for taking the time to share! Much appreciated!

[@hesa3656]

Thank You Sir! Those are amazing groups! 👍🇺🇸🎉

[@MansonReamers]

Kenny, excellent work with outstanding results. Thank you and the team at DPG for the business and keep up the good work!

[@jonathanseal5155]

You may well become the busiest gunsmith in the country‼️‼️ Congratulations on a logical, rational and repeatable method for building a very reasonably priced rifle with consistent topline accuracy.

[@albertoguerreiro006]

great job , and nice to see the phases of the process and watch this amazing results and this is put the cz in another level 👍

[@briansupermag3918]

Absolutely amazing work Kenny. You are making it hard to wait for my rim x build. Can't wait to get that call from you saying its time to start the build

[@javiersp01]

you keep rocking Kenny. Great Job !!!

[@donjohnson605]

Well thought out reverse helix reamer. I have had the best luck with that style for maintaining size and alignment. Great job! 👍

[@calebmartinez3805]

No argument man, you really improve that platform during years, excellent job, from a good rifle to a precision rifle!

[@jeffreypelletier7247]

Love the CZ stuff man thanks!!

[@johnmorrow5085]

Your gunsmithing talents,videos are the very best. Awesome work!!

[@Womfat]

Wow, very cool. Love you attention to detail and that thing is a laser!

[@dannyboy5272]

This is really inspiring for me as a relatively new gunsmith. Like you, accuracy is my number one goal given that it’s still reliable in operation.

[@milo555100]

Man. Good on you. Great job with your biz. I would love to have your skill and knowledge. I think about lathe work for rifles all the time. Subscribed.

[@blackprince4074]

I wish I was 30 years younger, then I would try this out on my 457. But at my timeline of life, I don't think it's going to help me.I am still having fun and enjoying the trips to the range for the companionship and camaraderie plus the BBQ at the end of the shoot. Thanks in my next life this is a goer.

[@fredshebester-wg4vb]

Seeing is believing! From an old machinist, it makes perfect sense

[@jeffreypelletier7247]

Awesome thanks for the info I have a 457 VPT

[@GetMeThere1]

Great video! Very exciting stuff. You're gonna be a VERY busy shop.

[@tomnielsen3661]

As always, Amazing! you have to feel pretty darn good after building that rifle and the way it shoots, As jonathanseal5155 said, you are going to be one very busy person, as word get out about what you can do.

[@treeratbuster]

That was amazing. I'd love to have saw the groups with the original barrel for comparison though.

[@eskimoreloader]

Enjoy your videos. Thank you

[@o2wow]

Hard to argue with great results.

[@jimgallagher5785]

That's just incredible! Nice work.

[@daverieck6352]

Love your work mate. Only wish you lived in Australia and you could build me one. Enjoy watching your videos.

[@YotaDaryl]

Amazing work = amazingly results.

[@arnoldmoos1791]

WOW, very nice work. I ordered one of your CZ builds in May, hope you are going to do this procedure to your new builds even if the price goes up.

[@EagleEyeShooting]

Hey Arnold! Yes any CZ builds currently pending aswell as new orders will all have this process done to

[@HigherPrime8]

I honestly didnt think I wanted another competition 22lr and I was pretty happy with mine, but every video I watch from Kenny it makes me want to order another and have DPG set it up!

[@Mrjaspgu]

I think the proof is in the results. Excellent work! Wish I could afford one.

[@CyclopsJoeVideos]

Holy Crap ! That’s a BEAST NOW . Great video Kenny

[@donalddepew9605]

There are always different ways to skin the cat so to speak. Great Video!

[@oldguyrimfire]

Great work! Have a Lilja barrel and xlr element with all their weights. It shoots great but it is not balanced! Frustrating since I shoot nrl/prs 22! Hope you allow actions to be sent in soon!

[@trevnorth2295]

love your channel, would love to have one of your .22lr in 457, but stuck here in the UK the chances of it happening are next to none please keep adding new videos

[@darrellryan2337]

This is the best. no doubt about. when your ready I want to send you my action. thanks for sharing.

[@EagleEyeShooting]

Thank-you! Soon as the new shop is all settled in and I have shelf space

[@jreedishere]

Is there some way to be notified when the time comes?

[@numizaairguns1373]

Awesome job and it's group like a dream...

[@martin2514]

Good stuff. Keep up the good work.

[@ibrahim10910]

This is mechanical art. So awesome to see.

[@brutushunting]

Magnífico trabalho parabéns.sou torneiro mecânico aqui no Brasil. E um apaxonado pelo cal.22lr. se fosse possível poderia fazer um vídeo com melhorias pra um cbc 8122 cal.22 lr E a arma mais em conta pra Brasileiro. Grande abraço e sucesso

[@conservativesniperhunter7439]

Do I think that your method works? Shit yeah it works and it works brilliantly. It won’t be long until Gunsmiths all across the country and overseas start building CZs the Desert Precision Gunworks way once they find your channel. Awesome gunsmithing Kenny 👍

[@matthewrezuke8130]

When can I send in my action? Those results are amazing.. great work.

[@thangcung1993]

God blessed you brother ❤

[@jeffsmth46]

Wow great job!!!

[@RimfireSS]

I’ve got a action I can send in, when you have time just say the word and I’ll send it. I’d love one of those truck axle barrels.

[@jackbippus2757]

Terrific video!

[@ralstonraz]

Crazy consistency. 🙂👍

[@robertbusato]

Awesome. 👍👍

[@davejones3923]

That is awesome love to have that done with my CZ 457

Great work from KSA 🇸🇦

[@Cyborg-911]

Good Job Bro!

[@cz503]

Great work. I am surprice that you don't have problems with 10 round magazines. The problem is showing with 10 rounds only, rifle run just fine with 5 round ones. Usually after barrel change the bullet is pushing high in the chamber which cause FTF. The cure is change the foots angle on magazine follower . By changing the angle the bulet isn't push that high - the angle isn't so stiff so no FTF. Another little trick of centering the lip /ramp plate- it has to be screw down with bolt closed. I have 455 with this problems and after fixing this the rifle is running like a tank.

[@EagleEyeShooting]

Any FTF issues are usually poor headspacing. The geometry of our custom fitted barrels are essentially the same as factory minus the grub screw relief cuts. I also add a polished chamfer on the chamber to aid in feeding. No issues with factory set 10 round mags

[@user-hp6qk3uv8p]

Really nice work ☺️

[@rawy310]

I know my next purchase. Can't wait get my hands on a completed rifle from you!😅

As Eric would say Believe The Target !!!

[@CP-ct5op]

Damn! I want one!

[@wilfdarr]

This is really interesting: I got a new bike last year and the aero seatpost kept slipping (over an inch per hour on the bike: I cranked it down that I've just about stripped out the bolt, but what solved it was shimming it with not one but *2* beer cans. In short, that slop is what causes movement. Now that I've got it shimmed it hasn't moved *in months* . My point is, I don't think it needs to be interference fit, just trued and matched to a larger diameter barrel to remove that slop. Then, you wouldn't need to press the barrel out because it's not interference fit, but I bet you'd still increase the accuracy significantly!

[@wilfdarr]

Regarding the above, I didn't know you guarantee 0.3 or better. In that case, I understand why you'd go with interference fit, for a few reason. Great build, great video!

[@guygratton2309]

Beautiful video and being a millwright ,what you did is brilliant and it shows on paper,I will call you to get one build,keep up the precision work,👍👍

[@jamespeacock7202]

Amazing

[@doyle201206]

do you have a video for before and after test shots to see if this was worthwhile to consider.

[@IY6C]

That was amazing video

[@martingagnon4547]

I realized I could wrap around my barrel tenon a full turn of scotch tape and still be able to fit it in the action!

[@rectifycustomguns2142]

While I have not kept track, I am sure I have not done the number of builds you have I have not seen the variation in roundness and taper you have in the CZ actions. I am using a bore gauge like that used to measure engine cylinders and other items when they are being honed. In the 0.709" range I don't feel like I'm able to get as accurate a reading with the telescoping gauge. Your reamer setup looks interesting, I have been using a less complex system to true the tenon bore and action face but it has produced good results I would agree that the large cuts in factory and aftermarket barrels would seem to create a bendable area right at the chamber when the set screws are torqued. Any taper or clearance fit between the barrel tenon and the action adds stress to the assembled action/barrel. Thanks for sharing your process.

[@EagleEyeShooting]

🤙

[@wilfdarr]

Ya I agree, using a T gauge and then measuring it externally like that adds too many variables.

[@krmcc01]

When will you do my rifle? I bought one last year it will group fair but usually on the 5th round I have a flier that messes up my grouping.

[@BillyWillicker]

I use dial bore gauges over snap gauges when I can. They are far better for that type of measuring. Expensive but worth the cost.

[@EagleEyeShooting]

I agree, but theirs always a better tool someone will recommend. I can say, well just use a CMM. But realistically, it's just a demonstration and refrence. The precision ground reamer and bushing verified at .710 ensures the bore dia is set to .710

[@BillyWillicker]

@@EagleEyeShooting My intent of my comment was just point out a faster, more visual method of measuring, not to discount your methods. The results speak for themselves, regardless of the tools used. By the way, I can't accurately measure tenths with snap gauges, it's why I use the bore gauges. Maybe if I used the snap gauges more often I would be better with them.

[@user-vs4bx1nw9h]

Very impressed with your craftmanship and dedication to improve on what is already great.Will all the CZ builds be receiving this new method on receiver?

[@EagleEyeShooting]

Thankyou. Yes, all current orders and new will receive this process

[@BY-dq3mt]

Awesome, I ordered a 457 barreled action a couple of weeks ago! The hard part is having the patience to wait. Well worth the wait. I may shoot a stock Cz in production in the meantime.

[@geckoproductions4128]

Very interesting video. I rebarrel Anschutz rifles and Achievers and I like your thermal fit routine and will try it. I use green loctite cylinder retainer and wondered if you had considered that. And if so, why you chose to use blue loctite instead? Thanks for the video

[@EagleEyeShooting]

Loctite 243 is resistant to chemicals vs green. I have seen corrosion caused with cleaning substances such as Hoppe's with green loctite. The tennon area between the action and barrel will be subject to our cleaning chemicals to pool and may cause this corrosion between. I do not need a permanent adhesive as the thermal fitment process suffices

[@swolbrink]

Excellent, the consistency must be incredible. Once you find the ammo it likes, do you ever shim the bolt for headspace to fine tune? I’m very interested in your thoughts. Thank you for doing these videos!

[@markthibault8579]

Wow. Very impressive work which takes the CZ 457 to that next level. Out of curiosity, is it possible to see how CCI SV performs out of one of these?

[@EagleEyeShooting]

Absolutely. 👍

[@isasolya8498]

Hi Kenny I have a question. I know that 26 inch barrel are best for 22lr. accuracy up to 200 to 300 but is it for longer shots ? I mean, as a 26 inch barrel is slowing the bullet speed compared to a 16 inch, which one is better for 400 to 500 yards ? Will the gain in speed of a 16inch help more with the accuracy at this distance or the 26inch will still be more accurate even if the bullet is more sensitive to wind ? Is there a compromise, like a 22 inch ? Thank you for all your quality work !

[@alandickson7991]

My current target rifle is an Anschutz 54 30 used in 50 Metre Olympic style shooting with aperture sights. The barrel on this is threaded at the tenon and screwed into the receiver like a centrefire rifle. The earlier 19 series Anschutz target rifles had heat shrink methods used to fit the barrels to the receiver. Have you ever experimented with threading the CZ action and screwing on the barrel?

[@howardjohnson5734]

hi what is the advantage or threading the action and barrel ?something to do with harmonic transfer ?

[@alandickson7991]

@howardjohnson5734 The advantage is a more rigid connection between receiver and barrel, which is conducive to better accuracy, especially with a floating barrel where the only connection of action to stock is at the receiver. It is also a stronger connection, important with the higher pressures of centrefires when the locking lugs are located in the receiver.

[@BrainFart0]

Nice work! Is there a difference in diameter of the action between the 455 and 457?

[@cristianartico3637]

jesus f c ...great job !!!

[@dcalero56]

This looks like it’s definitely 100% the rifle I ordered 😂😂

[@janthonydrivenpatien]

Hello you and your channel are awesome...you don't fall into the hype of just standard "mil-spec being just as good" mentality. Will you do an Ar-15 for me?

[@scottluther6699]

A lot of KZbins have commented on the great work Kenny has done. I’m not disputing that at all. Nor am I disputing the accuracy claims because I haven’t had Cz out to shoot yet. The weather has been bad, my tract scope hasn’t arrived, and I sent it off to get cerakoted when I got it. However, just wanted to say a few things. First the wait time for the rifle was pretty spot on to what they said, which was impressive, my experience with anything 7 months out, there’s always some unforeseen delay. Heck, cerakoting in 2 weeks got delayed 6 weeks. I asked to have the chassis cerakoted, they didn’t do it because they weren’t set up yet, you can order them from mdt that way. Not sure why you wouldn’t if your setup wasn’t going to be ready (did get a call a few weeks later saying they’d do it now). Kenny didn’t call before making my rifle to ask me about anything, just got the I’m done get me your FFL. Not exactly the KZbinrs experience. Didn’t talk about what chambering he’s using and why, didn’t ask if I wanted a 25” barrel. Would have been nice to get a logo engraved. Now the other issue. The bolt is so gritty and stuck I had to used my whole hand on the bolt to get it to open and close. I had to use polishing compound then sat watching tv while I opened and closed the bolt 1000 times before I could do it with 2 fingers. But it begs the question how he shot 20-30 5 shot groups and didn’t notice and sent it out that way. Who knows, maybe he didn’t personally shoot the groups. Hopefully the winter weather will give me a chance to get out soon. If it shoots as demo’ed then I’m a happy camper. The bolt works fine now. Got my gun cerakoted and passed on getting it engraved. Plus my scope arrived around new years. Just wanted to let people know that the KZbinrs and top competitors experience is most likely not going to be indicative of your experience. Makes sense since they provide the most influence. Then again, maybe my experience is the exception. Good luck and may your shots never stray from the black.

[@EagleEyeShooting]

You stated that you sent out the rifle to cerakote when you got it. If the cerakoted the whole action, theirs the problem with the grittyness. Sent an email to follow up. Thanks for reaching out. The picture of the rifle and groups shot was sent over after I testing your rifle

[@scottluther6699]

@@EagleEyeShooting I only sent out the chassis. Didn’t cerakote the action or barrel.

[@EagleEyeShooting]

CZ's are not a Rim-X or Vudoo in regards to smoothness. I built a great barrel for a CZ, I didn't build the action. They do wear in and feel smooth after a while. Go shoot the rifle and😉 I don't recommend a 25in barrel for a CZ due to the action design. Chamber and barrel twist is laser marked on the barrel.

[@Chickidy]

Scott, this is kinda disappointing to hear. I know you didn't get to speak with Kenny personally but you did speak with me. To be honest your rifle was a very straight forward build. I didn't feel the need to schedule a call with Kenny. We do have over 300 clients so Im not sure what experience you were looking for. A 25 inch barrel was never a question because we would never offer a 25 inch barrel for a CZ457. We also do not offer laser engraving as an option or service. Cerakoting setup did take longer then expected, due to delays in our shop not being completed on time. I did have Robi from dpcerakote reach out to you personally and offer for you to send your rifle back at a discount, just because I knew you wanted it. Dpcerakote also had no lead time when she offered it. Also, in regards to the chamber, that is all listed under our CZ457 in the description of the build, where you clicked to place the order for your rifle. Every detail about the chamber and specs is listed there. The smoothness of the action is also dependent of the manufacturer of the action. Kenneth always tests every rifle down range personally. We did provided you pictures and feedback of its performance. Once you finally get a chance to shoot the rifle and your not satisfied, please reach out to me on our website or give me a call. -Ashley

Can you do a 457 22 WMR? I'm getting old and would to have one 👍

[@jimc5708]

Wow!! Can you tell us a bit about the pedigree of the barrel you spun up for this trued receiver? Thx.

[@EagleEyeShooting]

Sure. Its a 24" 1.100" Straight Shilen Select match 1:16 with a custom chamber for Lapua

[@gordy1961]

I wish I had one of those.... I have a new/old stock CZ452, not round fussy but nowhere near as accurate as my old Voere semi-auto... anything I can do to improve it? I do have some engineering knowledge... thanks from over the pond...

[@jwoodshed1108]

Mine was the same. Only 0.0008 out. So there process is pretty good. I wont mess with chucking another one up. Im guessing they are all good enough. What temp are you getting the action? I dont want to heat it up and change the structure of the metal. You may warp the end or take the hardness out of it.

[@EagleEyeShooting]

Just enough till the oils start to smoke. No where near hot enough to mess up the tempering. You can see me handing the receiver bare handed. Also, no, cz457's are all over the place in measurements.

[@Skilpadjie1]

Honestly. I get that with my Sako Quad at 50 yards.

[@karlmullinax3621]

Nice…… but why do you tease us so, can we be friends? Great job as usual!

[@karencollins9363]

looks like the work was worth the results

My 457 is factory stock yesterday shooting 30 gr. WMR at 50 yards i could cover a 15 round group with my thumb. That's minute of ground hog all day long.

[@EagleEyeShooting]

Nice.. grab a cookie and a famous POB 🤙🫡

[@AlexandStuff]

Do you do this process to all your new 457 builds now? NVM, just saw your response to another person who asked this.

[@davidb7262]

How does the CZ preform at distance compared to the RIMX or Vudoo? Group sizes at 50 or 100 are one thing, but matches are generally one past 200 yards. Have you been able to test group sizes at 200 and 300 to compare the systems?

[@EagleEyeShooting]

I have, our CZ457 builds use the same barrels as our Rim-X and Vudoo. The performance is identical. The difference is feel of the action and non Rem 700 footprint

[@CraigTigard1]

When will you be accepting actions to true and rebarrel? I have a 457 standing by. Thanks

[@thefarguy1802]

How does one get in touch with you for service please ???

[@markthibault8579]

If a person truly wants precision, it seems that a custom DPGunworks-built CZ 457 will produce better and more reliable results than a factory Vudoo or Rim-X and at a better price. And, as a bonus, the mags are cheaper and more reliable. Seems like an easy choice.

[@hardcorefishermen]

so can someone explain how this work helps groups consistency without simply describing the work done or without it sounding like some vague theory?

[@EagleEyeShooting]

Rifles speak for themselves. Hundreds of cz457's we built winning matches across the country. Desert Precision Gunworks. You don't know what you don't know
