I've been able to get good accuracy from my T/C Hawken .54 with Power Belt "Aero Tips" and Hornady "Great Plains" 425 gn HBHP.
With PRB, not so much. But, this is probably because I don't know what I'm doing... I am using Hornady .530 and .535 swaged balls with .010 patches propelled by Goex FFg or Pyrodex RS. My barrel has shallow rifling and is probably a 1/48 twist, although when I tried to measure the twist I got 1/56, but my measurement method was probably lacking.
I've noticed a lot of expertise on this forum, so I am open to suggestions on improving my PRB accuracy...
