Greg,
I've been using the Lee C113 to good effect in a Marlin 1889 that I managed to get an 1893 barrel for. The original 32-20 bore was/is unshootable as is,,, and I managed to get what I would classify as a "fair" bore in same on Ebay. The newer barrel is shooting very well with 4.8gr of Blue Dot under a WSR primer and the unchecked/unsized Lee, ~.313" > .314". Minute of claybird shards at 50 yards dancing around on the bank at the range off my elbows. VERY satisfying after struggling to get any better than shotgun patterns at 50'. I got in on the group buy for the 6cav Lee offering, and have been pleasantly surprised how well it's doing without a check. I'll get a .314 size die and wind some up with some Lil Gun or 2400. No chrony data on the 4.8gr of Blue Dot, but I'm guessing 1100-1200fps. Neglibible recoil, and not a lot of noise, though I'm guessing by the crack that I'm over Mach 1.
I've also managed to crank up the Lee to 2300fps in the 30-30 with excellent accuracy,,,,, a great little boolit. Personally I'd like something just a bit more refined, but increasingly coming to the conclusion that I've got to start gettting Dan at mountain molds to custom cut for me. His online design tool is excellent.
Cheers,
