I have a 223AI bolt gun that I am about to start load work up. I am interested to see what powders are going to be best for me. I will be using winchester brass and cci 400 primers along with 75gr a max bullets. My oal is going to be 2.45 to the lands. I would like a temp stable powder. I have alliant AR-Comp on hand but I am not stuck on that single powder. Any advice would be appreciated.

Re: 223AI Powder
Varget and RL-15, Varget is one of the better temp stable powders for that round, you will get more fps from less RL-15 thou. Not sure how temp stable RL-15 is, haven't played with it much. Good luck!

Re: 223AI Powder
I have seen a lot of posts with the 75 Amax using RL-15 as well as H4895 and a few varget. Wish I could add more but I am still waiting on my barrel to arrive... I can say Varget and IMR 8208 work great in the standard chamber.

Using Benchmark here with the 75gr A-Max/Lapua brass and loving it. No fan of RL-15, but it gets hot here in Florida.

I used to run varget behind the 75amaxs, compressed to the max, hot as hell with wolf primers. Shot good.

Re: 223AI Powder
I'm about to start doing the same.
I am planning to start with varget since I Have 16lbs of it... kindof praying that it works for this application haha.
I'll be using 80gr amax though.

Re: 223AI Powder
This is what I came up with today while fire forming. This is 10rds rapid fire at 75yards with a 1-4x scope. I got down to the target and I was surprised.

From my 22" 1:7 223AI barrel, using Nosler fireformed brass and CCI-450:
26.2gr Varget with 80gr A-Max @ 2.485" OAL is 2890fps
26.6gr Varget with 75gr A-Max @ 2.48" OAL is 2955fps
I plan on using 80s from my barrel and am thinking of trying RL15, 8208XBR and 2000MR to eek out a little extra velocity. My 80gr A-Max/2890fps load is very accurate but if I can sneak it up to 2950 it'd be even better...
