So, I've had my beautiful 3-band for nearly a year now and still can't get any meaningful or consistent accuracy from it. I've tried various Lee Minie molds and then popped for the Lyman "Blue Gray" mold No. 578675 -- which I'd read a lot of good things about on here, and which throws a beautiful bullet of between 400 and 410 gns. These mike out right at .577. Problem is, I've never managed consistent 50 yd groups (let alone 100 yds.) with any of these bullets, including the Lymans, of less than 6-8" -- and sometimes much, much worse than that -- shooting from a solid bench rest. 1) I've been dip-lubing my Minies with SPG. 2) I use between 40 and 50 gns. of Triple 7, usually 45 for the Lyman bullets (which for a while showed promise, but not lately). 3) I KNOW HOW TO SHOOT -- I get fine accuracy with my two Pedersoli Hawkens in .50 and my Pedersoli Kentucky .45. 4) I have not so far been doing anything to size my bullets (see below).
Winding back to the beginning -- what should I try? What am I doing wrong? I've ordered one of the Pedersoli sizing tools from Flintlocks Etc. -- which lets you choose between .577 and .576. CapNBall, in his YouTube video, got great results using the Pedersoli 3-band with sizing a BIG Minie (over 600 gns.) to .576. But I don't want to use that much lead. Is SPG the wrong kind of lube for Minies?
SUGGESTIONS? I love shooting this rifle (Ok, rifled musket) but I'm going to lose interest if I can't begin to get actual groups out of it. Right now it seems little better than a smoothbore.
Thank you!
