I just started learning about BP and been working awhile on trying to figure things out and determine the best load. I think I have it pretty dialed in because of all the advice and input you all have given here. Yesterday, I shot a group at 2.8 inches at 200 yds and 2.25 inches at 330 yds. They were only 5 shot groups as I was testing loads but I think this shows the load is consistent. If anyone cares, this is what worked - 66gr Swiss 1.5 (weighed), 520gr bullet at .460 with .06 fiber wad, WLR primer. Wiped after each shot but still trying to learn this fouling control thing but it seems wiping does produce consistency after I've shot a few rounds. My first two shots were left.
