leaver evol. is ok for hogs, deer, and such but not heavy enough for really big game. i shot a hudge bison with my 1886 and did not get a singel pass through. 4 shots to get him to tip over , all in right spot from 76 yards. needs to be at least 400 gr or there abouts. how big? both sides hanging in butcher weighed 1100 lbs !!
