We shot the Optima stainless this weekend. The Accura has user adjustable trigger which would be nice, but we did well with the Optima.
We used White Hots and Powerbelt 245gr bullet. It was as accurate as any rifle I've shot. We cleaned after 3 shots. We thought the "kit" was a little expensive for what you get.
This was our first experience with a modern muzzleloader. Dad picked it up with the Konus scope package for 400$ from Cabela's. The bullets, powder, and primers are not cheap. But it was a blast figuratively and literally.
The stock is nicer looking on the Accura for sure. I didn't think much of the Optima stock as for the looks, but it was very comfy.
