Good morning all, After an absence of many years in shooting black power rifles (former CW reenactor), I have a strong interest in getting back into the swing of things again, having recently purchased a Pedersoli 1861 Springfield and Navy Arms Mississippi Rifle. (I was floored by the prices for new rifles as they have more than doubled when I bought them 18+ years ago, even from Cabelas). Anyway, when I used to shoot BP often, buying powder and musket caps were no problem. Now...different story as the store that I used to purchase from cannot afford all the red tape and regulations that comes along with storing BP. I have a few cans of 2f and 3F stored, but will use Pyrodex RS for plinking. Anyway, when I ordered some musket caps I had to pay the hazmat fee to have them shipped (this too was a surprise as I never had to do that years ago). My question: Is there a nipple that will fit the threads on my muskets that will take No. 11 percussion caps? If so, where can I find them? Thank you for your time.
