Neck Tension - Too Much?

[Woolsocks]

My new brass has .312 necks. I typically size to .314. Loaded round is .317

Would loading right into the new cases without resizing the necks be a terrible idea? 5 thou seems like a lot.

I personally run everything through my sizing die on the first firing for consistency because I want everything to be the same because of what my personal standards are.

If you are OK with some inconsistency which maybe, might, potentially open up groups by like ¼- ½ MOA...or might male no difference at all.... then.....

You're totally good on load and go for your first firing.....and probably on subsequent firings till you anneal on your 2-4th firing... or anneal every firing depending on how much work you wanna do.

Why not run a mandrel through the necks?

Get a 21st century mandrel die. I have 2 dies and buy the correct mandrel to size any virgin brass before I load it. The 30 and 6.5 mandrels fit in the short or long dies

I still lube but I typically buy the titanium nitride mandrels or whatever it’s called that doesn’t need lube

Run them over the expander ball in your FL die.

Mandrel+ a bit of drylube is the answer...

100 brass x 5 seconds/each = 8.x mintues ...
worth it unless you are really stressed for time.

Also, typically you want to inside chamfer, even
eg lapua, when its brand new...but ymmv

Okee dok. Sounds like 5 thou is a lot. I’ll expand and size to .314.

I have shot brass with more, but I always run new brass over an expander. It rounds necks so you get a good chamfer and debur. It might shoot it might not. You might trouble seating bullets you might not. You're the only one with hands on it. Best anyone else can do is what they would do.
