I had a Zouave for a while. It came with both a nipple for a musket cap and a nipple for #11 caps. These nipples were bored for blanks and were self cocking due to the large flash hole. I think the purpose for my inexpensive Zouave was to be a blank firing replica although it was rifled. The nipples were soon replaced. I sold the rifle to someone who wanted it for American Civil War Reenacting.
