Being old and many shoulder surgeries, I understand...so I put a muzzle brake on many of them...like its pleasant to shoot PRONE a 300 RUM with 250 gr Atip at 3000 fps and 101 grains of powder.. with a really good muzzle brake. I've shot 70 rds out of the 50 BMG from the prine on my 70th birthday...but I was beginning to feel that 60 rds of 50BMG is about right with my rifle...a muzzle brake is the key.
