I'm thinking about trying this.
I have a friend who wants to sell me some Norma brass once fired. Looking at the brass options, I want something that will last a while before the primer pockets get loose. There is Nosler, Hornady, Gunwerks, ADG and Bertram I think. Would any of those be better than Norma?
For dies I was thinking about Hornady to start and sending fired cases to Lee for a custom collet sizing die.
I also have a K&M neck expander and neck turning setup. I can anneal.
Some people mention cutting down a 375 RUM die to push the shoulder back. I don't understand what's different between that and just removing the expander of a 338 RUM full length sizing die?
Unless there is something I'm missing, it seems like I should just remove the Hornady expander and then either:
K&M expand (making essentially 338 Edge), trim to 338 RUM length, size in the Hornady die and then trim again.
K&M expand (making essentially 338 Edge), size in the Hornady die and then trim.
Size in the Hornady die, trim to 338 RUM length, K&M expand and then trim again.
Or size in the Hornady die, K&M expand and then trim.
After doing one of those, I'll ream and neck turn with my K&M neck turner unless the necks are too thin.
Which method should be best for making good concentric necks?
Should I be thinking about different dies?
I like the Hornady seaters with their micrometer stem.
I like the idea of a custom collet die so the brass won't be worked excessively.
Since I'm only going to use the sizing die for case forming and the occasional shoulder bump, I think I might as well get the Hornady set.
I would appreciate any thoughts or suggestions.
Thanks
