No shortages of .223 ammo around here at all. .22 rimfire is making a pretty strong comeback, as well. It's usually available for around .08 per round...
The .357 magnum has been proven to be just about the best "stopping" cartridge ever, when loaded with 125gr HP bullets... this data was collected from actual police/LE shootings back in the 80's or so. It beat out the .45 ACP, the .44 Mag.... ALL of them.
The big drawback is the horrific muzzle blast and flash that goes along with it. Shoot one in low-light conditions, and you are temporarily blinded for a few minutes.... shoot one out of a 4" barrel without hearing protection, and you'll need to go home and take some Tylenol and rest for a few hours.. then go get fitted for your new hearing aid...
ask me how I know....
This is a pic of Massad Ayoob firing one in low-light....
