OP, I have two rifled .62’s, two smooth .62s and two rifled .58s (well one is my sons Leman) plus several .50s, 54s and .40s.
Hunt with all of them. The .58 and .62 kill way out of proportion to their ball size compared to the smaller calibers.
.40 to .54 I try to put as much velocity on the ball as I can with charge weights up to 90 grns (I am not recoil sensitive and have tons of time on heavy recoiling military calibers), but the 58/62 just dont need it. 60-70 grains is more than enough. When you connect with one of those bowling balls stuff goes down and stays down.
If you hunt, you will love the .58
