We've been having these matches since April but one thing I haven't seen so far is what you're shooting. I know the loading data you're using from the match report but up til now haven't seen what you're shooting it in. If ya feel like it post a picture of your match guns for my entertainment.
Here's my two Lyman Great Plains Rifles and my Uberti 1851. I started with the caplock GPR but switched over to the flintlock when I got it a few months back. I think I should have stuck with the capgun but I'm in now and not giving up.
