Hello, I am looking at having a 50 cal Renegade re-bored to 54 for patch round ball. I am looking at having Mr. Robert Hoyt do it for me. Here are my questions.

1. Have any of you had this done by Mr. Hoyt?

2. For PRB .54 what twist do you use and how accurate is your rifle?

I know kind of general questions but any help would be appreciated.

He is doing a 50 to 54 rebore for me now, this will probably be a 1-38 twist for conicals. Ask Bob himself what twist and ask what patch and ball thickness and diameters he suggests. I would think between a 1-60 and 1-70, but that is just a guess. There is not much Bob does not know about barrels.

No experience with reboring a 50 to 54. My primary experience with a prb in a 54 is with a 38" Colerain barrel 6 groove radius bottom rifling (round bottom) with .016 groove depth 1-56 twist. Best shooting prb gun I've ever owned with my PA Mountain Rifle built by Gunmaker Brad Emig. Good luck with your 54!!

I bought a round ball barrel at auction recently that is 1:66. It seems that round ball barrels tend to be longer than the stock 26" Renegade barrel. Mine is 32 and the drop in barrels sold on TOW are longer too. I have not shot mine yet. Will put a post up when I do.

My 54 flinter is 1:66, and is much more than sufficiently accurate for deer. Five shots at fiftey yards is one ragged hole if I do my part. That's largely due to the peep sight helping out old eyes.

The rule of thumb for 54 cal is 1:48 is conical (Maxi ball) twist.... 1:66>1:70 works well with round ball, either .530 or .535 depending on the gun.

Mr Hoyt did a 50 to 54 cal change, rebored and rifled to 1:66 for me back in the mid 1980's. The bbl was won and chose from several items by me at a local shoot. The Numreich Barrel was a 42", .50 cal 1:66 twist barrel was a prize. There was a front and rear site mounted, 2 attempted staples in the bottom flat, the more rearward one was spot welded in an apparent attempt to firm it up. That made a slight swell inside the bore resulting in a tightened spot 2/3 the way back. You had to slam or pound the ball home. It shot well but it was still a bee...atch to clean with a jag. No problem with just towe. I was given Bob Hoyt's name, contacted him and explained the problem and HE suggested the resized, rebore solution to the problem. Took it off the stock; sent it as was; I got the barrel back in a timely fashion. replaced it in the stock as was sent and returned. I shot 5 shots from a bench rested setup, at a 25 yard pistol target set at 50 yards. 3 touching center X ring, 1 just touching at 7 o'clock on the center ring line and 1 at 10 o'clock, 2" out. I left the sights and Mr Hoyt will ALWAYS HAVE me recommend his work. Another member of the Loyalhanna Longrifle Assoc at that time, an officer took my recommendation, and had similar result experience. Just like the ol' redneck saying says: Git 'er Done!
