To keep this going, someone on another forum modified the SSS 60 gr. rounds by cutting them off at the front band, which made the round ~ a 53-54gr. He had some success with it, and it stabilized much better in his guns. They were said to be very effective.
I would like to see (I know, dream on...) a .22 LR 50 gr. With an effective hollow point, loaded to 1000 fps. (subsonic) That should be a real thumper.
Actually, I guess I could just buy some Winchester Rim Fire (WRF) ammo. It has about the velocity necessary, and a 45 gr. bullet, too.
WRONG,WRONG,
WRONG!!! No, it won't! WRF
WILL NOT! chamber in .22 Long Rifle guns.
It will chamber in .22 magnum firearms, though. Sorry for the wrong info, folks!
