I haven't run them yet, still having nightmares over the week-long decoppering project from the break-in (and I cleaned after every shot with copper solvent). Maybe the 380-400 rounds of PC cast at full-bore load levels has smoothed it out some. I was mainly remarking about the care Sierra and some others seem to be taking toward throat fit with cartridge-specific bullets, and I'm glad to see it.
