I’ve been dialing in a .54, all groups were shot at 100 yards, point of aim was the inside tip of each triangle — Ive tried sighting in this gun often on with various combinations of different powder quantities and granulation, patching, etc, and never achieved anything resembling a group after the first few shots. It always opened up dramatically after just a few shots.
Last week, I shot target #1 — this gun always has a drastically low flier on the first shot, so flier circled on each target. Using 80 grains Old Eynsford 3f, .540 roundball, .018 pillow ticking patch lubed with spit. First group (admittedly only 2 shots after the flier) was decent. Second group opened up quite a bit, as always. I cleaned the bore quickly, not a deep clean, and shot the third group which tightened up again somewhat instead of spreading out even more. Not great results, but I was satisfied that progress had been made.
Today I shot target #2, using 70 grains 2f Swiss, .540 roundball, .018” ticking lubed with mink oil, slightly smaller triangle but same point of aim, the inside tip of the triangle. This time I cleaned very thoroughly between each group, and the results were somewhat better, I would like to tighten it up just bit more but this is the most consistency I’ve seen from this gun, after doing the one thing I always resisted doing before, cleaning thoroughly between each group.
Has anyone ever found that some guns just don’t shoot unless they’ve been scoured after every few shots? My lube and powder changed between target #1 and #2, but as mentioned I’ve tried many combinations of powder lube and patch in the past and they all yielded the same lack of consistency after a handful of shots.
The patches don’t tell me much, I was only only to find a few last week, today I picked up a bunch but when I got home only 1 was in my pocket, but it’s pretty representative of the ones from today’s session — would anyone suggest that they’re still too frayed up? The patches from last week were sufficiently cut up that I switched from spit to mink oil as mentioned
