Thread: loading for 223

I am still load developing for my 20inch AR15 but 24gr of ADI 2208 on 55gr is giving me 1inch MOA in a 1 in 9 twist (Stag model 4). 23.6gr is my next load to try as I only have 5 x 55gr projectiles at the moment. 62gr does better for a 1 in 9 getting under 1inch but that is also under development but around 23.1~23.6gr of 2208 seems probable (A factory load of 77gr SMK PMC is under 1 inch). Currently handloading 77gr and I have a box of 69grain also, (I suspect 69gr is probably going to be the best weight for the 1 in 9 twist) just waiting for my shed to get warmer, LOL, 20rounds and I'm frozen

BM2 seems a good powder to try though ditto 2206H. The former is on my list of powders for future tests, but waiting on my Caldwell Chrono to come from Brownells, tablet to run it came from amazon 2 days ago!!!
