YesBought some new unprimed Peterson brass in 6.5 RPM and was wondering if I should run it thru the full length resizing die before loading it?
This is really the bare minimum, first firing you are forming your brass to your chamber.Chamfer debur and run a mandrel through it. Done.
i'm not sold on that, but doesn't mean that SOME are and SOME aren't from factory.Factory brass is already undersized for SAMMI chambers. Running them through a FL die doesn't make sense to me. How do you set the die adjustment; based on previous brass?
I normally just run a mandrel into the necks to ensure that the necks are not out of round. Using the mandrel, I've noticed that some factory brass has particularly tight necks. I'll also chamfer the inside of the case mouth before loading.
Wow... Just how many cases make that FL die 10 times? Before case head separation? Annealing every time? Trimming brass every time? What a headache....Everything gets run from new to 10 firings through the FL die. Consistency!
I'd say it depends on the brass and cartridge. Circa late 70's and early 80's super-x 264wm brass i fl sized over 20x w/o any neck splits or case separations. Will I ever seethat good of brass again, I'll may never know?Wow... Just how many cases make that FL die 10 times? Before case head separation? Annealing every time? Trimming brass every time?

You should make it more clear. I bet you are not FL sizing, but just bumping the shoulder.
Your statement raises questions of your process.
