e.g. Ruger Single Six comes with two cylinders; one for 22lr and one for 22wmr. Projectile will happily go out the same barrel, but the 22lr case would likely split and cause you harm.
Recommendation 1 = don't do it.
If you survive, next you can try a 20g in a 12g; will not end well.
Recommendation 2 = don't do it.
Recommendation 3 = I'm sure someone has already tried this and posted it on YouTube; look there instead of doing it yourself.
If the .22 longrifle was meant to be fired in a .22 magnum.....it would be stamped on the barrel. where is the common sense?
