Will be taking delivery of a 1-28 .54 GM barrel [Renegade]@ the end of this month and was wondering if will be able to use my Lymans 450gr Plains mold or TC 430gr Maxi-ball? Not interested in sabots.I see in the fast twist White rifles they are using 535gr and bigger so hopefully I 'm not going to need a custom mold to shoot it.Perhaps I should have ordered a 1-70 ball twist?Any and all feedback welcome.........Harold PS any advantage pro/con to changing this over to musket caps?
