I run it thru, if nothing else it will take any dents out of the mouth, then check for length, trim if needed and do the mouth chamfering before loading.

Treat new brass as you would once fired brass. Resize, measure, trim (if needed)and debur/chamfer...

and a third vote for treating new brass as once-fired.

+ whatever with everyone else. Size em.
I once had new 45 Colt brass I didn"t resize. Loaded several rounds and the bullet would rotate in the brass. I tightened up on the crimp and smae problem.
Pulled and sized all the brass. Problem solved. A learning situation

Do Not know how to enter a new topic, but . . .
It's getting extremely difficult to even find this forum on-line. For those who still can, please send me the secret. I'm not a computerwizard, so the secret shall remain safe with me. I only know how to shoot and record results. Please don't shut-me-out of weekly conversations. I learn a lot from this truly-strange forum: Pro-gun or Anti-gun, not yet fully comprehended. I hope this forum is here to assist true gun-advocates. I own but two rifles, yet I feel I have much to contribute firepowerwise. cliffy

Guess I'm the odd man out
I don't resize new brass. Not entirely, anyway.
For straight wall cases, I'll check to see if the bullet is tight. If not, I'll size them. If so, I'll flare them.
For bottleneck cases, I'll run the sizing ball through the neck. Usually, I notice the necks for new cases are tighter than spec. But If I do a couple and there is very little resistance (indicating the necks are properly sized) I'll see if a bullet fits tightly. If it checks out OK, I won't run the sizing ball through any more.

+1. Except, I use a bushing instead of an expander ball.

Ive got new Winchester brass that was slightly undersize before and I could manually put it into my sizing die and remove it with little resistance. Nonetheless I like to resize that is just my routine for loading.

The other thing that full sizing does:
Verifies there is a flash hole. Had 1 in 10's of thousands that didn't. Dang near bent my decapping pin.

Depends on the gun for me.
On bolt guns:
I neck size only - on brass that is pre-fired that will be use back in the same bolt action rifle as long as it doesn't need FL resizing. If it rechambers just fine I will neck size only. My .270 is longer that most others I've seen in the chamber, so I can't close the bolt on my ammo in other guns.
If its needs FL resizing, I just chamber the re-sized case to check it. If you are too long it won't chamber. The problem can be if you are off by being too short you may not know it. I take a long case & FL resize it till it fits tightly & then slowly screw die in til the case fits right. Putting a reference line on the die helps.
I'm going to get some measuring equipment to be able to check & document case measurements.
On AR & semi-auto ammo I resize & use a case gauge, Trying to size just enough to put the case as close to the longer limit.
It is a lot easier if your case lube is working like it should. Some case lubes gave inconsist results. Range pickup & mixed headstamp will also give some variances. Often on semi autos I end up picking up all the brass on the ground so FL sizing on all of it.
