On the matter of hollow points expanding. Hollow points need velocity (and not to be plugged up) to expand. Out of my Marlin 60's 22 inch barrel a Super X or simmilar may become an old Roman Coin. Out of an NAA single action, well, I think someone has a YouBoob on reloading .22lr, that undeformed hp will do nicely. Velocity, its hard to achive in little short barrels, be they .251, .311, .357, .421 or .451. There is a guy here who carries a PPK/S in .22lr (and that's fine, its a neat little gun, with good shot placement it can defend you). BUT, he carries it because the box of .22 says 1510 fps, and .38s are like 750 -900 fps, so thats like ALMOST TWICE AS MANY FOOT POUNDS.
