Reloading 300 Blackout Ammo - Converting 223 / 556 to 300 AAC Blackout.

A short video showing the steps to convert 223 / 556 to 300 AAC Blackout!

I need a pot of coffee and a couple of hours with this guy......

And maybe a few range days too..

[@JustinoFundido]

when I was learning how to do this my resizing die was around 1/16th inch to high. The round wouldn't chamber. I had to go and take apart 500 rounds. A case gauge is a must. This video is gold!

[@burnsrandy]

I had to do the same thing, thanks for your comments. Eddy

[@Tedthegreatwhitehunter]

Case trimmer and caliper

[@jamesvatter5729]

This is by far my favorite 300 Blackout reloading video. Straight forward and no, "You gotta buy this crazy expensive gadget that we just happen to have in stock." Thanks, Eddy.

[@burnsrandy]

to Brian Cowan, The expander that I use is made by lee. It's called a universial case expander. It comes with two expanders. one is smaller for lower calibers and one large expander for the larger calibers. It expands the case mouth as much as you want. I expand my case just enough for the bullet to just start into the case to eliminate the case from shaving the lead or jacket off the projectile. Brian if I am not explaning this well, let me know and I will try another way with pics. Eddy

[@Adamorevo]

Your explanations include triple redundancies. It is clear, you have a history of teaching and instructing. Who needs a pappy or grandpa to learn reloading. We got KZbin and you. Damn good stuff Eddy!

[@derekbeyers8804]

Very good 👍 I like the detail and the explanation of everything. Talking slow and thoroughly. Very well done sir! Thank you

[@LBoss222]

Eddy this video is just exactly what I was looking for. I am gearing up to load 300 blackout for the first time. Thanks for sharing your knowledge, great video. it's been 2 weeks since I posted the first half of the comment: I reloaded just over 100 of the blackout rounds and test fired a few...thanks for your great videos, they really helped.

[@Bruce23d]

One of the best techniques videos I have watched on 300 blackout case development!

[@JamesS.254]

I'm just getting into 300 blackout and this video has helped me out a lot. I have a ton of used 223 brass with dents near the shoulder from ejecting out of some AR's, and this method will bring new life to formally unusable brass. Thank you for sharing your methods with us.

[@JohnVHLife]

The dents will come out when you shoot it again, dented brass is just fine.

[@code3responsevideos872]

Awesome video! Better then all the other 300 beginner videos. No confusion and I understood exactly how and why everything works.

[@rguy57]

Imagine being this gentleman’s apprentice. Amazing knowledge. I hope they have a knowledge capture plan.

Yeah, I was having flashbacks to junior high woodshop where the dude behind me cut off four of his fingers with a bandsaw.

[@TaintedMojo]

Yeah, that got me cringing too

[@sissonsk]

Well Shoot! I need to get a 300 Blackout upper now. I have a couple thousand 5.56 once-fired brass and I want to get a .30 caliber upper for my AR. The fact that the .556 bolt will fire a 300 blackout and I can reload my 5.56 brass with 300 Blackout makes the 300 Blackout a winner.

[@100nortonfan]

Thanks for sharing your knowledge! It is very informative and is a lot of help in learning the process before laying out money for tools and materials.

[@hk93shooter]

I had issues with foreign brass, ppu, s&b because of the thickness of the case below the neck. I now use only american brass, LC, remington is the perfect case wall thickness for converting. .011 to .012 is whats needed. Thanks for the video.

[@Bobshell-tw8xy]

Great info Eddy. I’ve watch quit a few of your vids. I’ve been reloading for 20 yrs on the same Dillon 550. Now I’m doin 300 BO on it and I’m trimming and sizing all in same pull from Dillon trimming and sizing die. What a time saver. It does work well. I respect all u do and how u do it. But I’ve often wondered why no Dillon equipment. ...thanks for the info. And god bless Texas ...

[@burnsrandy]

thanks for the comment on the shirt, we tried hard to properly explain the problems encountered when reloading.

[@pep729]

I just started loading 300. Might be important to mention the wall thickness at the case mouth should never be thicker than 0.014. 0.013 or less is optimal. Might depend on your barrels chamber as some have tighter tolerances than others. You can either sort your brass to known good head stamps or just neck turn them all. A simple hand neck turner can be had for about $100 and as much as 300 ammo is these days it will pay for itself with the first 200 or so rounds. I have nor the time or patience to sit and check head stamps sometimes I can't even see so I just turn them all. You don't want to work the brass too much. I stay around 0.013 - 0.012. Also as you stated the neck OD should never exceed 0.334 after the bullet is seated. Don't solely depend on a case gauge. Use your calipers to measure. No need for a micrometer unless you're measuring for competition loads.I've had quite a few pieces of brass that were on the "bad" list and would get stuck in the chamber but once turned they were good to go. Great video!

[@senster7717]

Great video. I have the same saw and I use a jig to cut the brass and I use the plastic shield that came with the saw so I don’t cut my fingers off

[@killerb5726]

No wonder why this ammo is so expensive... 😂😂... All seriousness, great job and great video.

[@thetobaccoguy1751]

Excellent video. Will be diving into this when my next suppressor clears.

[@EFLO3D]

All I learned from this video is I'd rather pay 77 cents per round.

[@MikeNaples]

You have to love reloading to make it worth the effort. For me life's too short and I don't mind paying for the expensive factory ammo. Don't get me wrong, I've great respect for the reloaders.

[@g19.58]

Nicely done!

[@rojasray]

When u remove the cut case, I cringe when ur finger get about a half inch from that blade. Dude, re-think your process !!!

Excellent -Thank you for sharing your knowledge!

[@grantpickens2704]

Thanks for your time and knowledge!

[@jacktheaviator4938]

I respect your thoroughness, but if you are having to trim the cases twice, that means you didn't cut it right the first time. If you used an adjustable stop on your chop saw, and get the length set right, you wouldn't have to trim it twice. And your chamfering fixture for the drill press is cool, but why? When you chamfer a case, you aren't taking off much. Stick the tool in, spin it once and you are done. Using a power tool for chamfering looks like a recipe for short cases. If you are putting so much effort into chamfering that you need a power tool, it's a sign that you aren't chamfering, you are shortening.

Hi Ed Just getting back into reloading after 40 years. Starting with 300 BLK. Do you think 223 brass is better to make 300 blk cases? Thanks Harold

[@eddycoleman1232]

yes I do.

[@backnine]

@@eddycoleman1232 Hi Eddy Have done some 300. Found out a Lee Die will not completely form the brass. Bought Hornady Custom Grade die set and worked perfect. What is the reason to resize the 223 before cutting. I use the 300 case gauge to check. I will run into a few that will not pass the gauge. Same brass 223 brass manufacturer. Great Videos Harold

[@equuspallidus]

Great video eddy.

[@mybuickskill6979]

Sir I have a question. I'm a new reader and I believe this to be a bit advanced for me. But wouldn't a bit of annealing post second(300 black out) resizing be a good idea? Especially if running fire 223 brass after a couple reloading sessions.

[@goodwater2020]

Thank you Sir.

[@wildlife321]

Thanks for the info. Please forgive my ignorance...but why do you need to size the case, before it is cut?

[@eddycoleman1232]

just to be sure it is sized correctly, the 300 blackout doesn't size as well around the base, my opinion.

[@jaysonbowe2747]

just getting into 300 blk pardon my ignorance but I have to learn why not cut the case at the right length rather than cut deburgh then trim deburgh?

[@jjed100]

good stuff, getting the 300 reloads to chamber has been a problem

[@gwill9472]

I'm a touch confused. OAL on this 100gr rnd is? Length of the case trimmed is 1 5/8" or 1.0625, or 1.3625. Factory ammo is at 1.355 So I'm getting lost. 2400 powder is 16.9gr I dropped to 15.3 but level is still near the neckdown part of the brass. Seems like a lot. I did a few neck downs by hand. Fun! Can you drop me a note, let me know your thoughts. I'm out of spring, tx.

[@wiggsan]

Excellent! Thanks!!

[@flysubcompact]

Well done, instructional video.

[@mariewingert6516]

check your inside diameter of the case throats forming cases from another cases causes. build up of brass in throat a 308 inside reamer will help or outside case turning will solve problem been doing 300 whisper for years

[@eddycoleman1232]

excellent suggestion

[@BK-oo1bl]

I know your video is older but I didn’t know if you said anything about swaging primer pockets on 556 brass or reaming out the pocket to get rid of the military crimp I know from experience it will smash the primer but I was lucky they didn’t go off

[@wiggsan]

Hi Eddy! Could you please tell me what the meaning of the 'C' on the end of a measure in grains in a reloading chart? For example, 19.0C gr of IMR 4227. Thanks!

[@kauboy9816]

You might know by now but that "C" is used to indicate a "compressed" load. Meaning you will be seating the bullet directly onto the powder because the case will be full.

[@casehatch1378]

I'm ready to do my insides

[@dfabove9108]

Well done sir!!!

[@zackbaumgardner4937]

remove the handle on your cutting device, screw standard nut on instead. then you could simply use a drill or impact driver to zip them down to size. just an idea?

[@EastTexasOutlaws]

[@zadien8409]

Can someone explain why you'd check the length of the cartridge if you are just gonna cut it shorter?

[@LooseGravel14]

Please, just tell us which and how much powder, over all length and bullet weight.

[@princepscivitatis2140]

Awesome info

[@tylerkirchoff4559]

NICE THANK YOU

[@henrydando]

How long do you cut the .223 brass too?

[@RTSchramm]

Eddy, I have three questions: 1. How did you check the length of the cartridge, if the cartridge is too long it won't go into battery? 2. Do .223 and .556 cases require a different powder charge if using the same brand of powder and grain bullet? 3. How many reloads do you get out of the .223 brass? I have tons of PMC .233 that I would like to cut down to 300 BLK. Nice video, but you need to be careful around that saw, I see you been cut at least two times recently before making this video.

[@eddycoleman1232]

In my opinion, no. Ck case length with a case gage. If you need help, let me know, I will do my best to make it clear.

[@eddycoleman1232]

The book gives you a case length, subtract .010 from the length and this will be your trim length. this is standard on all rifle cases.

[@eddycoleman1232]

If your shooting for accuracy competition you should develop loads for each, but for hunting and plinking you want see much difference, feet per second changes a little and might shoot a little high but not enough to worry about.

[@Aardvarko]

Great video Eddy! I was wondering though, have you found that resizing the 223 to a 300 Blackout reduce the life of the case? From what I've seen normal 223 loaded and reloaded properly will usually be useable for about 5 reloads depending on the circumstances, is this reduced when you change those cases to the 300 Blackout because you're doing additional resizing and trimming?

[@equuspallidus]

Anneal the brass. You will get more than 5 reloads.

[@joejeans7913]

Safety first!

[@daveycrockett9408]

I belive at the end your talking about brass wall thickness, being able to use and resize foreign and some american brass will NOT work well or at all!. I use only lake city brass after cutting and sizing, I'm getting a constant wall thickness of around ten thousands, or a pinch less.. Iv'e seen some foreign brass at 12-13-14 thousands, and is way too thick to chamber or = go into Battery!.. So a .308 bullet at .308 + 0.10 + .010 for each wall = 0.328 thousands at your neck. you are correct at .333 + will start to be hard to chamber in most 300s or not at all.. Everyone should be checking their wall thickness at the neck right after forming, and chamfering inside and outside of thier cases..........

[@Homale74]

America 👌🏾

[@nvbeav]

Thanks for your video! Question from the 2 minute mark: The Closed Captioning says you sawed off at 1-5/8". Should that be 1-3/8"?

[@chadparker8198]

I think he means to say 1.58... still once he necks it down it will be less. My finished brass is 1.58 and has room to grow after firing.

[@nvbeav]

@@chadparker8198 Thanks... The specs show a case length of 1.368" which is close to 1-3/8" (1.375"). Of course, the cutting length doesn't include the resizing yet (shoulder & neck forming).This is getting a little confusing.

[@useruser400]

Just buy Hornady 190 gr Sub X and call it a day. It’s incredible and you won’t handload anything better. I’m an avid 300 BLK shooter, a handloader, and I don’t get paid by Hornady for any endorsements. By a box. You’ll see I’m right.

[@joshuawilliams4160]

What 300 blackout dies are you using?

[@brianlee2255]

Save some time if you size them before you press and de burr, wont you? Seems like you double handle

[@stevenfry3442]

Why is it a good idea to resize the brass prior to cutting it to length? Thanks

[@JamesS.254]

When the brass is resized it is bending the brass to the desired shape, in doing this it will shorten the overall length of the case. So if you cut it to length before sizing it, the case will come out too short after sizing. Just remember once you remove the material you can't put it back. So you're better off being slightly longer because you can remove more material if needed. Hope this helps.

[@shooterscorner7500]

Great video, how did you determine the 0.030" over cam on your single stage press?

[@eddycoleman1232]

trial and error

[@eddycoleman1232]

When the full length die touches the shell holder, thighten the full length die 1/2 turn more, you will be close.

[@MrMann-gt1eh]

Is annealing unnecessary?
