Do not know why, but the bore diameter of the 54 Hawken Barrel and the 54 Renegades are different. The Hawhen is much tighter, the .542 slip fit both Renegade barrels, and the Trade Rifle barrel just right for me. You can get a .542 to go down the Hawken fairly easy once it is started on a CLEAN barrel but on a fowled bore it really get tight. Dan has a 54 Hawken up ther and the .541 is what he had to use also, both his Hawken and Larry's have the QLA.
I really do not, or have not yet, get the the best groups with these 420/54 cal conicals that I really would like to see - way acceptable but nothing like what I can do with the 460's... I really wish they were a little heavier and a little longer... think that would make a big difference...
