Lol, the reason i ask is because I've always wanted to use the tape primer while shooting. I know most use caps when they shoot the 1855, but it's a personal dream of my own to shoot a musket with a tape primer.I asked the same question many years ago, when I had a fairly robust M1855 collection and unbelievably DuPont still holds the patent, which they apparently renew, at least that was what I was told by a fairly reliable source. I used to reenact with a '55 and wanted to find the tape primers, but I never bothered to follow up, on the veracity of the claim. My '55 collection is down to the nub (1) rifle (2) muskets and my favorite, the Cadet.
I don't even think there is footage ofsomeone using a tape primed musket anywhere, If anyone has that please link.
