I tried the main one on their website and it just rang for 5 minutes. Anyway in the mean time i suppose i could tell you why i need to call them. I started sizing/depriming .223 rounds on a single stage and no matter how much i cam over the press i cant get the die to bump the shoulder back far enough. I am checking this with a dillon case guage and verified that it is not going back far enough by making a dummy round and putting it in the ar-15, yep pretty sticky on extraction. The problem seems to be that the shell holder (that came with the lee dies) is too thick for the die. I would just file the shell holder, but i know there is no way i am getting through tool steel that way. I have read of people with the same problem using "stones" to take 2 thou off the base of the die....but i would rather not. IF anything ill pay to have a machine shop take some off the top of the shell holder, if lee has no fix. Suggestions?? Phone number??? Thanks guys.
