Keep yer hair on, some of us are considered "essential" employees and are working lonnnng hours.
I shoot a Parker Hale P58 Enfield in competition. I use the RCBS Hogdon sized to .576, 42g 3f Swiss, RWS caps, beeswax/lard lube. This combo in my gun is a sub 2moa rifle. My other competition Enfield is a "musketoon" and shoots the same load with pretty much the same results.
Now to your question. What Enfield? Repop? Armisport? Euroarms? Pedersoli? Original? Parker Hale? These things matter. The bore sizes can vary widely especially in the one made in spaghetti land.
Some basics-
1) KNOW your bore size BEFORE buying any molds. For best accuracy, the minie needs to be about .001-2 under actual bore size and that doesn't mean what's stamped on it or what you THINK it is. VERIFY.
2) Use only real black powder. The subs have their own problems. Use a quality powder, not some reenactor grade crap. I shoot Swiss or Old Eynsford in competition.
3) Use good quality caps- RWS or Schutzen. CCI reenactor caps are for blanks are are garbage for accuracy.
4) When purchasing a mold, get a good quality one that you KNOW will fit your gun or better yet, get some sample minies from CWBulletman and then buy the mold for the bullets that work best. Generally speaking, ONLY one Lee mold I have works in any of my guns and it's not like I haven't tried. That one is the "target" minie that looks like a trashcan. It will shoot the lights out in my gun but gets unstable near 100yds so it's a close range only bullet. The downside of that particular Lee mold, they discontinued it in 58cal so I bought a couple backups on Efay because Lee molds aren't the best in quality. The Lee mold you mentioned will not shoot better than 12in at 100yd in my gun, a nonstarter for competition.
If you really want to know how to make a musket shoot, try hanging out with us in the North South Skirmish Association. We shoot Civil War era guns in competition up to and including artillery. Yes, we live fire Civil War cannons in a competition format.
