I had one for a few years. I liked it fine at the time. It shot pretty well too but pounded the snot out of me. I also found it NEEDED to have the 209 conversion because the #11 caps would frequently fail to go off. I didn't mess around with them long because I knew when I bought it I'd get the conversion for it. In the end, I found it a PIA to clean, it was heavy too, but I still liked it for what it was.
With the advent of easy to remove breach plugs and break open actions, I sold it off for a different muzzle loader which I've been really happy with.
If you like Rugers, and I do, it's fine muzzle loader. If I could find the officers model version, I'd consider another one just for the collection.
