Hi fellas, I'm needining to buy several expander plugs for my Lee universal expander die. When I talked to a guy at n.o.e, he seemed to stumble a bit when I asked how many thousandth of tension I should have on my pistol boolits. I asked about .358, .359, etc. I never really got a solid answer from him. Anybody have an answer? I hate ordering the wrong dang stuff as I have a terrible time getting my mail in the first place. Any help is appreciated. Thx
