What makes this 1-48 twist barrel that much different then say the 1-48 twist of a T/C Hawkins or Renegade? Is the rifling cut different? I have a .54 Renegade that shoots maxiball real well, but normally I hunt with REAL conicals 300 grain out of it. It shoots them real good and they really put a hurt on a deer. I am wondering if this would also shoot REAL conicals well.

Also what is the normal asking price of one of these?
