Has anyone shot one of these? Wondering if ignition is as good as the claims?
Yes. I have had one for about 3 years now. Got a Doe 2yrs ago in our late flintlock season, (PA). I have taken it to the range several times and have never had a problem with ignition. Providing you follow the instruction book. TC recomends using Pyrodex pellets, or loose Pyrodex or of course Black Powder. My friend got one and had trouble with ignition. He was using 777 pellets. After I told him to use the recomended Pyrodex Pellets and didn't have trouble afterward.
I have one and it's always worked fine for me, but I've never used anything but real black powder in it, so I can't speak for it with the pellets.
