What kind of "short" shotgun? Mossberg Shockwave style?? I have both the tradational under barrel tube magazine as well as the removable Magazine styles to play with. Very tote able across chest/under arm/on back for rapid engagement with modified BooneyPacker sling. And with practice and a Crimson Trace LS-250 SaddleLaser, I find the Shockwave to be very effective for close action.......on stationary and moving target, not toothed/clawed critters yet thankfully. Does take several boxws over several days practice to handle the slugs and 3" buck, but can be developed just like shooting .44 magnum, 460 and 500s. I'll deal with the recoil damage after the threat is turned off. If not turned off, recoil damage will be least of concerns. Also, evaluating a SRM1216 semi-auto semi-bullpup (18.5"bbl; 32.5"OAL; 7.25lbs empty) with 16+1 capacity......4 rounds in each of 4 rotating tube magazines. Can load slugs, buck, shot in any tube and rotate to desired tube. 4-tube mag quickly swaps out to reload or change to other type rounds.
Slugs are lethal, with great penetration, but only hits one spot which might not be the immediate OFF switch in a one-shot or die scenario. Thinking maybe 00Buck might up one's survivability with also good penetration ,but provide more probability of hitting "turn out the lights circuitry" rather than slugs penetrating but not striking the OFF switch. Bear's brain sits lower than most realize rather protected by an armor-like skull. Head on shot, one would want penetration up the nose to follow the nasal passage into the brain for lights out NOW effect. Slug would either hit the nasal route or not. The 00buck might have more probability of hitting the nasal-to-brain route and also put out the eyes. At that close "I'm gonna die" range, not gonna worry about olfactory senses. Anyone else with comparative thoughts on slugs vs. 00buck performance.
