.223 reloading for an AR
The answer is likely here and the subject beat to death but I don't see it. I just got a Colt AR15 in .223 and plan to reload and am looking for the best recipe to duplicate the military specs and for the cleanest burn. I load for old rifles in .45-70 and .45-90 and have 5 shotshell presses, but have no experience with this little bottleneck wonder of a cartridge and will take all the advice I can get. I have reloaded for 300Win Mag in the past so am familiar with bottleneck cartridge reloading. I'll take advice on the best 55gr fmj bullet to use also- brand and source.

The closest thing I've found to a milsurp load would be the following ...
Bullet: 62 gr. FMJ Powder: 22.5 gr. of Accurate 2230 (A warm / in the middle charge) Brass and Primer: Lake City with CCI 450 Small Rifle Mag Primer. A word of warning .... don't shoot Remington 6 1/2 in your AR reloads. The cups are too thin and have been known to slam fire. I would use either CCI 450 , Winchester small rifle primers, or Remington 7 1/2 . Last edited by riverwalker76; March 10, 2010 at 01:03 AM. |

What is the twist on the rifle???
The optimum bullet weight depends on it.

Shoney is right it will depend on your twist rate.

If it is a Colt, it is likely 1:7 twist...

I've been reloading for ARs for about 6 months, so I'm only a little ahead of you. I've tried 55gr bullets and 40gr bullets ( I do a lot of varmit shooting.) I use H335 powder at published loads, and have never had a problem with cycling or pressure. IIRC, H335 was one of the original powders for the AR.
My point is, the AR should digest any .223 load that is within published specs, no?

What riverwalker76 said....also, you can go one step up and use the CCI M41 nato spec primers and for all intents and purposes, you will have a l.c. round. minus the anealing and crimping. The M41 primers have a harder cup and negates most slam fires. i have had good luck with them.

Bob's gun shop in Norfolk. I was T.A.D. up there and went messing around the other day. Walked in and they had a bunch of them large and small rifle sitting on the shelf. I about had a heartattack. Them realized that i flew in and could not take them home. Luckily, one of the guys new a guy that was headed back to south la. and took them home for me. Were a little high, at $36.50 a thousand..
