Thanks for the info bigblock. I never really got super into the BP other than building kits for fun, but I got more interested when I started doing some accuracy work with this x150 I picked up on the cheap with two barrels, I scoped the 45 and left the 50 with some tru-glo's on it. Using 80gr of Triple 7 and shooting a cast Lee REAL bullet, usually all shots touching at 100 with open sights and even better with the scoped 45. I think the REAL bullets were the trick a buddy cast some up and he swore by them, now I do too, I never got that accuracy with power belts or sabots. Thanks again for the usefull info!
