Ive been reading the posts here and on 450 bushmaster.com.
I have an impact slug of my throat (sizes .453) Barrel is mcgowen blank 1-18 twist
I have a mold on the way from Accurate 45-280B that will drop at .453 (hopefully)
I just got some taller gas checks made for the 450B.
I have some surplus wc820, H110 and LiL Gun.
Just so I dont reinvent the wheel has anyone else gotten the 450B to shot better with cast in the AR.
Any advice?
