Hey All,
First post on here. As a preface, I am relatively new to reloading. Been at it for the last 3-4 years, but I reload a lot more sidearm than rifle cartridges, so I would appreciate yalls input on trimming rifle cases. I currently have 2 different ways to trim rifle. One is the is Frankford Arsenal Case Prep Station, and the other is the Lee Power Trim, and each index the case differently. The Frankford indexes off the shoulder and the Lee indexes from the base. I find that I get a few thou either way with either one.
I have access to a machine shop and 3D printers and would like to make dies that I can fit into a progressive press so I can speed up the brass prep. Resize, trim, and swage progressively. I envision something similiar to the Dillon RT1200 / 1500. Obviously I would use the 3D printer to build the models and then machine them from steel after I have a functioning prototype.
My question for you folks is, is there one preferred way to index the case over another that gives you the most consisten results based on your preferred brass trimmer. If you could give me the pro's and con's of each that would be appreciated. If I'm gonna spend hours designing and machining I would like to know that I'm going in with the best info possible.
Before I get blasted for not just buying the Dillon Trimmer or something similiar I am just looking for a tinker project and may be able to build a few for friends. I am not looking for benchrest accuracy but would like the tolerances to be consistent'ish. Thank yall in advance.
