For plinking I like my .22 LR, for personal carry I prefer my .38 special or my .40 S&W. Not a fan magnums, hand cannons hurt your hands and if you fire one in an enclosed space, say goodbye to your hearing. Biggest round I ever shot was a 105mm Sabot round out of an M-60A1 Main Battle Tank. Good times!

Wish they would of kept it going. 45acp to 50AE Im like ahh no .450 Bushmaster or .458 SOCOM.

Don't know guns etc. What would you use that first bullet for (.17HMR or something) and I presume that last one is for A-10?
