[QUOTE="Trickymissfit, post: 475223, member: 25383"] I figured .001" clearence in the I.D. would be plenty. As for opening up the neck on the die, the best way to do it is with a Sunnen hone. But that would be the last thing I'd consider doing. I'm more concerned about the cases he's using than anything else. I went thru a coffee can of mixed once fired brass from just about everybody, and the biggest neck O.D. I found (unsized) was .251". Love to see a chamber cast, because I have a feeling that he's one of the very lucky ones that have a minimum spec chamber (I'll even go so far as to guess it's a Savage as they tend to cut their chambers tighter than most do). If he were close by, I'd invite him over for a try with someother die sets to get a second and third opinion. This brings into the grand revelation for the day! I have three bags of virgin .223 brass plus a couple coffee cans full (about a lifetime supply!). Well I cut one of the bags open and remove several cases for a measurement. I discover that the cases have absolutely no burr in the flash hole, and it almost looks like they were reamed! I go and pull another handfull with the same results. Next I check one of the coffee cans and get the same results! (now I hate deburring flash holes almost as bad as cutting primer pockets) After looking over a hundred or so cases I decide my eyes are playing tricks so I check the cases out with a probe; there are no burrs! How can this be?? gary [/QUOTE]
