pgp pierce pin
i'm having some problems with the pierce pin in my pgp
using crosman 12ies (they're available) i can't get it to puncture certain cartridges under about 250FPS
is there any way to adjust it so it will work?
every time I change the 12g, i have to turn the velocity way up, then re-chrono
I love sucking the juice out of pickles. -slowerpig81
