I been trying to get this rifle to shoot prb, it has a 1:48 barrel. I gone through different powders goex,pyrodex ff and fff .015" .018" .020" patches, .530" and .535" hornady and speer balls.At 25yards it shoots great,go out to 60 yards I be lucky if I could hit a cow. The load the likes at 25 yards is 80-85 grs. of ff or fff.I notice the patches are torn and burnt. It doesn't matter what patch thickness I use. Wound a fiber wad help out? If so what could a guy use for a wad for the time being? The shoots the Hornady Great Plains great, I would to hunt with a prb. Thaks Hippie
