Have killed a bunch of porkers with rifle rounds covering a large part of the caliber spectrum. My favorite is here in my hands, #3 buck at about 20 yards. That particular gun has accounted for about 70 hogs in its day, none required a repeat shot. Anyone doubting the efficacy of close range shot might not have a lot of experience with such things in the field. Fug a bunch of shield theory....it's not so much the gun as the jerk behind the trigger that gets it done.
Nicely done, sir. At the ranges we're talking about, even the shot cup will blow through 1/2" plywood. Some folks just don't respect a shotgun properly.

the only real difference between a good tracker and a bad tracker, is observation. all the same data is present for both. The rest, is understanding what you're seeing.
