.....Since we were traveling light, I took along my .357 Mag SP101 and my old 1911A1. Don't worry about ammo...you can find seriously-heavy handgun loads at the local WalMart. I grabbed an 18-pack of “Alaska Backpacker” .357's using a 200 grain hard-cast, gas-checked LBT.
Upon returning home, I chronographed a few and found them to produce 970 fps from the 2 ¼” SP101. Recoil was noticeable but not unbearable. The load's velocity didn't impress me much- until I started shooting things with it. It easily bored through a 3 inch seasoned oak limb, digging an inch groove in the trunk behind. It shot through an old mower deck- that .45 hardball only dents. This load grouped into about 2 ¼ “ at 25 yards, and the point-of-impact with the little Ruger was only 3” high at that distance. I do believe Alaska Backpacker's 200 grain .357 would shoot through a bear's noggin' and that's about all you can ask of a pocket gun. Truth be told, I would have preferred some of Buffalo Bore's Heavy .357 as it produces better velocity from short barrels. I wouldn't run from CorBon either but neither was available when I was looking for them.
Regardless of the ammo, a .357 is really too light for this duty. If Alaska were my home, a .454 Alaskan or short .45 Redhawk would be my constant companion. The .44 Mag has also proven itself time and again, and my choice of the .45/.454 is based solely on my sticking to one caliber.
