I’m not a fan of rifles for turkeys, however growing up you were allowed to use them. The best turkey killing guns used back then were a savage and maybe some other brands that were 20ga/22mag or 12ga/223 over/under. Back when we were allowed to kill with rifles and it was kosher, that’s what the killers used.
But 50 and in 20ga with tss 9’s is more than capable.
