Preferred powder for .223?

RE15

It is good enough for the AMU, it's good enough for me. Plus, it works in .308 rather well also.

Again, Worked mainly around a bolt gun,

Not a gas operated M14 or M1 Garand. Different burn rates required.

Props to Mr. Fettig, the man is a reloading nut.

Yeah, I'm certain that anyone that retro-fits lathes to turn their own .308 bullets falls under this category

Aaaaah, true. With the .308, RE15 is pretty much a "bolt-gun" powder. That said, it works great in a gas-operated AR chambered in .223 OR a bolt-fed .223.

Well, who ever dreamed up that RL15 is not meant for gas guns better call up Lake City and tell them they should not be using it in the M118LR! RL15 has the same burn rate roughly that of stalwarts for loading M1Garand and M14......like that of IMR4895 and IMR4064. And, LC loads the ammo for M24 M40 and M14/21 Weapon systems so me tends to think they know a few things about powder and such! Seems to me that the AMU might too? But then again I could be wrong....but...........not this time

TAC is great powder mid to heavy wt bullets in the 223! H335 is great for mid wt. Varget spans the whole wt range just sucks for progressive reloading...

I use 24.9 gr of H322 with a 50gr V-max. That has always given me <0.5 MOA/5 shots and sometimes as good as 0.34.
This is with a bone-stock Rem 700 VS (1/12 twist barrel).
I have been trying RL-15 with the heavier Sierra bullets through my AR15 but haven't been able to do much better than 1 MOA yet, but the gun and me are pretty new at it so both need more work.

IMR 4198 and AA 2015 both work for me, I use mostly the IMR 4198 in my 223's and 221.
