If I have a custom reamer made from the dummy loads I make up and send to PTG, I shouldn't need custom dies right? The chamber should match perfectly, no fire forming, and all I'll need to do is size the neck and slightly bump the shoulder just like normal at that point?
I appreciate your guys help and patience with me. I've only been reloading 18months, and haven't ever had a custom reamer or dies made. I'd hate to buy the Redding type S die set, then have to get custom dies made after. I guess I don't see the benefit of customs at that point.
When you size down a 300 case to 7mm, does it lengthen the neck any? One issue I think I could have with my Forster die is, I don't believe I can adjust the depth of the sizing of the neck, or how far down towards the shoulder. It sets up simply to bushing size the outside neck and bump the shoulder back .001, which is great-normally all you need. Does the Redding die allow you to adjust the amount of the neck being sized?
#2 How would you guys proceed from this point? Step by step.
My thoughts are...get new 300wm brass or take some of my old fired stuff and-FL resize it, then step down the neck to hold the 7mm rounds.
When would you turn the necks for uniformity? After sizing I assume, or before? Also annealing-before or after sizing down?
Anything else?
