I have a CVA Hawken style rifle that I purchased used and never shot, so I go to the store to purchase the basic supplies. I did some initial research online and the entire process seems pretty straight forward except for the type of cap. I saw four different types of caps - 209, #10, #11 and musket caps. The staff at the store was not much help, they recommended calling the manufacturer, which I may do if I don't get an answer here first. Any help.......
