I aint a big guy, and was pretty short n scrawny as a kid.
150s in a .30-06 if it has a decent recoil pad aint nuthing to fuggup ones shooting.

Used to be shotgun for deer state, slug guns were pretty brutal and some way worse than others.
Im sure many shooters were ruined before transitioning to rifles.

But spending time on ranges, I think most folks suck at shooting no matter what they run.
