Anybody here yet had a .54 Great Plains Hunter (the shallow groove fast twist) rebored to be a round ball shooter?
Probably end up a .56 bore? Use .55 ball?
 
This reply will sound like a repeated post, but Bobby Hoyt is your man. I had a Lyman Trade rebored from him, 50 to 54 and what a difference on accuracy! 1 in 60 twist, 7 groove, .011 groove depth, .540 bore. Tell him what you want to shoot, round ball size, powder load, etc. and he'll make it a shooter!

Agree completely. Followed his advice on a TC rebore to 58 caliber - radius groove, narrow lands, with a 1-60 twist. Liked it so much had him do another one. Now have one in flint, and one in percussion.
 
I cannot even remember anymore which is the first job he did for me.
Might have been putting rifling in a Green Mountain .62 smoothie drop-in flinter barrel. It's a TC Hawken, the one named The Rattler 'cause that what it does to the house windows.


Hope someone has had a .54GPH rebored. Would love to hear how one turned out.

Holy cow. Me too. Two .58's, one flint and one percussion. Same rifling.
 
Anyone have contact info for Mr. Hoyt? Want to have him take a .50 TC Renegade and make it a smooth bore. Hoping it can be a .62/.20ga but a .58/.24 ga would be ok.
