I hear all different methods for reloading and need some input. I have 100 pieces of Norma Brass that is once fired in my chamber. Would you neck size only until it gets too tight to chamber or would you use the "Inovative Technologies" die to size just above the Belt ,followed by the Body die, then neck size?
After one load I'd just neck size, unless this brass is hard to chamber. Thereafter I'd pay attention to how hard it is to chamber. If I felt too much resistance (and that's hard to explain in words) I'd use the body die to bump the shoulder back by .001" to .002" and then neck size using a Lee collet neck die. From then on you'd probably need to do the bump and neck size every time. I've been reloading belted magnums for several years and have never had a need for the Innovative die. I've just never had the problem this die is supposed to fix.
I typically full length size but just push the shoulder .002. I've done quite a bit of measuring on my Norma 300 WM cases and find that the Forster FL Bench Rest Die sizes the area just ahead of the belt by about .0005-.001 and hasn't been an issue.
I'm quite sure Mr. Willis' collet sizer is excellant. Seems it's somewhat like a Small Base size die; if you need it, nothing else will do the job so nicely. But, if you don't need it, well.....maybe it's still like a SB die?
