What Ian said, in its entirety. I give about 1/16" of compression, just to snug things up and keep the kicker charge in place.
Only the 45/70 has required a kicker. When I load WC-860, I load it like black powder--by volume, and not charge weight. I do scale the charges to get a "read" on actual weight for purposes of communication with others, but actual loading and charging is done with a Lee dipper for the 6.0 x IMR-4198 kicker, and enough WC-860 to give a powder column height to allow that 1/16" of snug-up I spoke of above. Accuracy is first-rate, about 1.25" @ 100 yards with the Ruger #1 and 1.75"-2.00" with the Marlin 1895 (Ballard rifling). Lee 405 grain bullets.
The only anomaly observed involves brass with 10-12 shot histories. At the point where the bullet case rests in the case, a small burn-through occurs that looks very much like the burn-throughs we used to see on paper shotshells where the hull met the edge of the brass base. I heard from one source that similar things happen with BPCR brass that gets long in the tooth, but I have little time-in-grade with BPCR.
