yikes looking like around $40 to replace them which i will definitly do shortly. i ran 12 caps through after i cleaned the pistol up just to dry the oil and it all seemed fine. would really like to burn some powder this weekend, would it be safe to run 20 grains of fff goex through and use the existing nipples that are on it now? i have the wonder wads for over powder and ball, bought some .454 Hornady rb's and i have bore butter but if it is a tight fit like i have been reading i would not use the bore butter. any suggestions? again i will order better nipples but would like to burn some powder soon, ya know the whole kid at Christmas thing!
