About 20yrs. ago I had an SKS and bought some 'hunting ammo' (not American made). After perforating a deer several times in a long repeat track and jump shoot I finally got it. Little holes, little internal damage found in autopsy. Those 'soft point hunting bullets' looked good but lookin' good is never enough in a hunting bullet, is it. I was sick and disgusted.......thankfully my first shot was low in the lungs, but the holes filled with blood and let the poor thing go farther and live live longer than I ever wish.
I do not blame the cartridge, and neither should they, however, if they have lost confidence in their equipment perhaps something else is appropriate.
I suggest a 45-70, never again could it be said there wasnt enough cartridge.
