RE: 22-250 or .223 ranges
NVMIKE no I have only shot 223 AR-15s . I am shooting .224 75 gr Hornady A-Max with a B.C. of .435 and S.D. of .214 he is shooting .243 58gr Hornady V-Max with a B.C. of .250 and a S.D. of .140 . Wind drift is a big factor ,shooter skill is also part but the big thing is the 243 bullet is losing stabilty at the longer ranges IMO.
