Having ZERO experience with shooting Round Ball, Is one of these more accurate than the other? I was invited to attend a competition type shoot this Spring/summer that is Round Ball only, I have 3 different Stock 1:48 Twist TC barrels in .54 Cal, I would rather have a Slower more dedicated Round Ball Twist. I just recently bought a brand New Lyman Great Plains Hunter .54 Cal (Fast Twist) i am leaning toward a Round Ball Barrel for it? What Caliber would you guys recommend .50 or .54? Does one of these seem to be inherently more accurate than the other?(like certain centerfires are) This is gonna be for pounding targets only. As most of you know I shoot Peep Sights, i already have the Lyman 57GPR Tang Peep on the Rifle, the Round ball barrel that i get will definitely get a Lyman 17AEU Globe front sight. Peep sights ARE allowed at this event, but my Paper Patched bullets are NOT allowed. Would a 1:70 Green Mountain Barrel be a better way to go than one of these Stock Lyman GP Barrels?
