Well I tried to find pics, and most of what I find online is him boinking that really hot girl in the cemetary (NOT WORK SAFE). And if you DON'T have hollow points, carving X's isn't too bad. It's low tech, but doable.
But until I actually see the flick, it's hard to figure out what it is.
Looks like a S&W Model 19 to me, but I'm not 100% sure about that. I had no idea how practical it was to carve Xs into standard ball ammo to make hollowpoints. I've heard of it being done, but personally, if I were gonna do it, I'd rather use a vice and a hand drill. Or just go buy factory loads.
