Well, was going to order the shell holder and length collet to trim some 7mm weatherby magnum brass. Got on midway usa, they don't have it, emailed them, and apparently lee doesn't make one for the 7 wby! Soooo,, my question is without having to scratch my head too hard (and the crowd on the forum is so good at questions like this) is there an interchangeable length and caliber round that I can switch in? I think the 7 STW is as close as I can come up with, its trim to length in the manual is 2.85", and the wby is 2.55", I guess I can grind off 3/10 on the length pilot and make it work since the heads are the same size also? The rem mag is 2.50" trim length in my manual, really didn't want to trim my brass .05 too short. Any other ideas?
