LIProgun, as you said, these are what I use, and are safe in my Mdl. 57 and Marlin Lever Rifle, .41 Mag.
.
First, the load with which I killed the 400 pound black bear was... New Rem. cases, 210 gr. Sierra J.H.P., 20 grs. H2400, CCI Mag Primers. This load is TOP END! I emphasize, the bear was treed and NOT charging. I was about 20 yards from it and fired one round which clipped the heart, penetrated a lung, and snapped the spinal column. It was a through-and-through shot and I never recovered the bullet. He was dead within about 15/20 seconds after hitting the ground. (Do not start with this powder amount! Work up!)
Today, I use a Beartooth Hard Cast, gas check bullet, 250 grs., Long Flat Nose, behind 20 grs. WW296, or H110, with mag. Primers.
My plinking or fun loads are 215/220 gr hard cast with 13 grs. Blue Dot.
Again, if you like these loads, work up from 10% below what I've listed. As we all know, every gun is a bit different.
My rifle in bear country is a .338 Mag. The reason I have the heavy handgun(s) is because in camp, cooking, sleeping, working around camp, cutting firewood, etc., carrying a rifle is nearly impossible. That's why I carry the handgun.
If I have to tangle with a bad bear, which I do not want to do, I hope I have my .338 in hand. If not... then the heavy handgun will have to do.
Best of luck. J.B.
