The bore is so tight that the ramrod paint is coming off due to it bending so much while going down the bore. I can't even get a powerbelt down very well.
The Jb's will work wonders, Sabotloader did 100 strokes down his very tight Triumph barrel and now can use mmp-24 sabots with no problem. i shot some full bore conicals out of mine and 30 strokes of JB/oil and it worked wonders.another thing is make sure you removed all that grease or whatever it is T/C puts in new barrels, it's a bear to remove it all.
