To me 'cost' of end product doesn't enter the equation. I like being able to roll my own whether shotgun, rifle, or handgun. Plus if you like to use black powder you can do that too. I maybe shoot 0-100 loads a year .... So no need for store bought loading 'equipment'. I did buy a 12 gauge Coach Gun for fun and defense along side my single shot.... But hand gunning is my main priority.
On another note, I bought a couple Short Lane Adapters
for shooting .22 and .45Colt/410 for the heck of it. Not really practical ... but fun and different
