My 16" 336C .30-30 accounted for a Bull Elk last year. 200 yards, right through the heart. Perfectly, cleanly. The 160 grain LEVERevolution performed better than expected. The Elk just folded. Dead Right There. Couldn't have done any better if I was shooting a .300 RUM. Bullet entered just behind the front leg on the left, hit rib bone, vectored through the lungs and heart, hit rib again, and exited the far side leaving a hole the size of fifty cent piece. This was a lot more damage and penetration than I thought I was going to get.
