Just spent the afternoon shooting revolvers, the smallest being a 4 5/8" Blackhawk in 44 mag, and the biggest being a 8 3/8" 500 SW. Kinda weird to consider 475 Linebaugh and 454 Casull as "intermediate handgun cartridges", but that was how the day went. Anyway, got me thinking about a backup gun for close range "surprised in the timber" situations. I can hit a 12" plate, offhand, 8 outa 10 at 100 yds with all my big revolvers (give me a fence post or tree, and that's 10/10). It occurred to me that they'd be excellent for shooting in tight spaces that my 300 WM would just be terrible for. Anyone here have handgun hunting experience? I'm curious what sort of "minimum values" are ethical for something like elk with a big bore handgun. 1) Impact Energy 2) Impact Velocity 3) Sectional Density I have a 4 3/4" Freedom Arms 454 Casull, and it chucks a 300 gr XTP mag at about 1550 fps. It's a handy "little" gun that's perfectly suitable for hip carry and shoots 3" at 20 yds offhand. My gut instinct suggests that would still flatten an elk at 100 yds (4" drop, 1100 ftlbs, 1400 fps), but I have absolutely ZERO experience with handgun terminal performance.
