In the wild you cannot always depend on getting that perfect shot. In addition, hogs are extremely tough animals that can be very hard to put down & keep down. They are not too fond of then idea of being shot. I have been charged many times. These monsters have very sharp teeth and know how to use them. I used a BAR 7 mm Mag. for years. I finally decided I wanted a gun that would put them on the ground & keep them there. The 1895 Marlin stainless 'guide gun' in the very powerful 45/70 does just that. I am charged NO more! Would like to try that 450. You caught my interest!
