Welcome to the forum. I have an identical rifle, and they are a lot of fun to shoot. There is a different learning curve with a flintlock than a percussion, so be prepared for some frustration along the way.
Before you start shooting, be sure it is not loaded. Take the ramrod, and lower it in the barrel. Grip the ramrod where it protrudes, and lay the rod alongside the barrel. The rod should reach back to the touch hole, or very close to it. If it stops a couple of inches before the touch hole, there is an obstruction, and it is probably loaded.
