I've killed three elk in my life,all with a Sharps. Two were with a 45-70, and one with a 45-110. Both rifles used the same bullet, a 510 grain round nosed paper patched bullet cast at 30-1 driven by black powder The velocity on the 45-70 was 1190 fps and the 45-110 gave 1310. Both rifles gave complete pass through penetration through both shoulders and about a 1 1/2 inch exit hole out of the opposite shoulder. All three elk were down in less than 30 yards. No blood shot meat, you could eat right up to the hole.
