I hopefully learned some about shooting a muzzle loader after my first a Zuave in the mid 70's. That thing on occasion, would have a delayed or hangfire of a few seconds. It is quite a experience to pull the trigger, have the cap fire and not the charge, start to lower gun and have it go off. Once I learned how to keep the channel open, and how to load, it was a very good, accurate rifle. I won a number of turkeys at the club turkey shoots. I shot it for several years, until the edge on accuracy was gone. Surprisingly, I had the most trouble using musket caps, so I switched to number 11 caps.The fellow I sold it to, got elk with it.
I always shot a fowling shot of a full load, before shooting for score. I used a .575 patched round ball and I believe 60 gr. of FFg black powder. For hunting I believe I used 100 gr of FFg.
