I want a .54 Cal with a round ball twist. I already have 2 T/C Renegades 1 with a .54 1:70 twist and 1 a .58 cal 1:70 twist drop in barrels. I also have a custom built (beautiful!!!!) hawken full stock .50 cal Flint Lock and I have a Jonathan Browning .50 cal Percussion with a 1:60 twist and I want a .54 cal percussion rifle with a round ball twist I am leaning towards another Jonathan Browning and/or a GPR. What do yall fella's think? Here is my thinking....Jonathan Brownings are beautiful yet parts are nill... GPR's are a dime a dozen, parts are everywhere, and they are tack drivers, but they they are made in Italy and Brownings are made in the good ole USA and very unique and are tack drivers as well. What do What yall think? I am selling a T/C Renegade in .54 Cal with T/C fiber optic sights, a .54 Renegade barrel with a T/C offset scope base, and a T/C Renegade in .50 cal to fund my new rifle. I have a T/C Big Boar on Gunbroker right now being sold paying for the .50 Cal Jonathan Browning I just purchased. GPR vs Jonathan Browning?????
