That reminded me of something I almost forgot. Some years ago, in the 1990's, I worked up a load for another friend & his Remington 270. The best shooting load in it was with 140gr. BT's - Hornady I think, BTSP's IIRC. The load escapes me now, but was likely H4831 and the velocity was just over 3,000fps, with .75" accuracy at 100 meters of double bags.

He shot one bear with it, in the ribs at about 70 yards, the bear collapsing at the shot. He said the entrance hole allowed him to put his whole felt-pack boot into it - Sorrel's I think he wore - LOL. He said something exited as the exit hole was larger than the entrance hole, not much left in between, but it was a decent bear - 5 or 6 year old, maybe 250 or 300 pounds - before the shot - 6 1/2 footer.

He got some 150gr. Partitions and we played with those after that experience - and 1" groups sufficed for his moose loads. Most guys around here shoot moose from 25 yards, out to 100yds or so.
I did have a 200yard shot once and took it, with my 9.3x57. THAT bullet blew up, too.
