Thread: How much is over fill in 223

I do reload sierras 65 - 77gn but still using BM2 for it, I achieved good groups but not "high" velocities in the way I see(2800ft/sec), please, any considerations? I am thinking in try BM8208 or 2208(09) for those projectiles.

Thank you in advance.

Loads used in my CMMG AR15 with a 16" 1 in 7 twist barrel

25grs BM2 with Hornady 60gr SP projectile MV 2850fps Group size about MOA

23.5grs BM2 with a Serria 65gr SP projectile MV 2695fps Group size slightly better than MOA.

22.5grs BM2 with @xring custom 69gr HPBT projectile MV 2520fps Group size about MOA

Only punched paper with these loads so far but have a Goat Hunt lined up to see how they go on animals.

I'm hoping the 65gr and 69gr projectiles will be good enough to take Goats Cleanly out past 200m if so I'll try them on a Deer or two and see how the perform there.

I also tried the 77gr serrias with BM2, it's showing promise, but i need to complete load development, accuracy wasn't MOA but it certainly was good enough to Hunt with.

I also use AR2206H and 55gr projectiles with good results in my Baikal single shot.

Smashes the Goats real good.
