[Hot Tabasco]

I would caution that along with more air pressure comes the danger of a pellet continuing on for some distance.

Wow, thanks for the caution, never thought about that.........

Just curious, with your knowledge, what's the difference between a .22 cal. PCP pellet, a .22 cal. break barrel pellet and a .22 cal rimfire bullett?

A pellet is what it says. A pellet. Typically projected with air.

A rimfire bullet is what it says. A bullet. Typically fired with gunpowder.
