Feel a bit remedial here that I'm not seeing my way clear on this one.
Have the Lee ultimate die set which was working great with the JHP BT Hornady amax slugs. The .308 slugs slipped just fine into the newly fully resized brass cases. I notice that the dies do not flare the mouth of the case, which is fine for .308 jacketed, but a little less fine for the .311 sized powder coated bullets. When attempting to use a dummy round as a depth gauge for determining proper setback from the lands, seating and subsequently pulling the slugs, the case mouth is shearing off the powder coating, and was stuck in the bbl such that I had to use my 22 cleaning rod to poke it out. They are GC design slugs, but there wasnt even a gc crimped on when this happened? Should I be flaring the case mouth? Sizing smaller?
Just got a sampler from one of the fine board members here, and many were sized to .311. How might one go about seating the slugs without shaving off the lube/powder coat? Bell case mouth? How? With what? Run them down closer to .309?
Looking to go sling some today, but I wasn't sure on this one.
Forgive the newb question, but ya can't be too careful about these things.
Many thanks CB'ers
