Most lever guns chambered for 45 colt are plenty strong to handle these hot + p loads. Problem is most do not have a fast enough twist rate to stabilize these heavy for caliber bullets. Henry’s 45 lever has a 1-16 twist but as mentioned the chamber is too short to function with anything heavier than a 260 gr load. I'd carry what you shoot well and bring extra ammo and speed loaders if a wheelgun and extra ammo in clipazines (that’s funny now @Stomper) if an auto. Cats and dogs are not hard to kill. Bears? That adds another problem and if they were present I probably would be packing a rifle.
