Views on this caliber for a short range shot? Winchester Trapper
I played this one a few times here but it looks like it's time once again:
This good sized caribou bull is one I killed nearly 2 years ago with my 45 Colt M94 Trapper. The distance was closer to 200 yards than 100. The bullet was a "300" grain cast from either a Lyman or RCBS mold with a weight closer to 320 and a start speed of 1500-1550 fps. The bullet first made contact with a shovel on the antler - punching a neat (large) hole. It then poked a hole in the left shoulder breaking bone and traversed diagonally through the body exiting just in front of the hip point.
Like every other caribou I've killed with cast bullets there was no tracking involved - maybe 5 seconds going in circles before they tip over.
Long holes seem to work just as well - if not better- than massive holes.
