OH, I have lots of boomers, but my nickle plated, REM. 870 Marine Mag.with rifled barrel, stays straped on my back when rafting AK. I kind of think of it as a 7 shot .727 caliber rifle. I'm just getting bored with the "lead slugs", and needed something to tinker with..besides the 730 grain Dixie Terminator. It only penetrates 42" of gel.
