i bought the
Stony Point Products O.A.L. Gauge
i got sick of fooling around.
it cost 50 bucks to find out what my chamber dimensions are.
god this pisses me off sometimes.
ok im done venting now........
at least this way i will know beyond a shadow of a doubt.
if anyone needs to borrow this stupid thing after i use it once.
i will need it again in a few years when the chamber has eroded a bit.
