hello what i have is the Ohio Ordnance HCAR , more or less a modern vers of the WW2 B A R ,i have the 16in barrel vers with 3006 , what im looking for is a good round that hit like a full 24in barrel vers . Been shooting 150gr but was wondering about the 178 gr solid copper rounds from Barnes . have also looked at the 210gr ammo from HSM ,this will be more like a close range weapon to 300 and closer so was looking for hard hitting that you
