Ok guys, full disclosure, Maillemaker and I belong to and shoot with the North South Skirmish Association and there are others on this board besides us. We compete with Civil War arms in both speed and accuracy and that means not only small arms and minies, but artillery as well. We might know a thing or two about minies. Since the OP only has 10 posts, I'll suggest this, use the Search function. Not to be snarky but we've been down this road many times already. There is no mystery to getting a minie ball gun to shoot well if the barrel and gun are in good condition. Follow the basics and you will most likely be successful. Use commercial minies, or alloyed lead, and all bets are off.
After reading the Search function results on minies, a couple things need to be settled before we can help you. First off, have you measured your bore? I don't mean what Pedersoli says it is, it HAS to be measured. It seems Luigi just can't get a bore exactly right every time. Second, we need ALL your load data- cap brand, powder brand and "f", lead type, bullet size, lube and loading methodology. Third, your casting methodology- alloy, temp, type of pot, etc. Finally, there's lots of bad advice and "reenactorisms" floating around on utoob. Be very skeptical of who you take advice from.
But what would we know about shooting minies?
