I always do but that doesn't mean I need to. I just decided it was better for me to do that than to wondering about if I should have done it.

"Is it necessary to run them through the re-sizing die?"
Well, it's unlikey to cause the cases to collapse, is it?
"Re-sizing" is, by definition, sizing after firing but why not try one each way and see what happens.

Load a small batch without resizing, and see what happens.
I loaded 100's of .223 from new Remington brass without resizing.
It all worked fine in my AR-15.

One would hope not.
However, returning them after they are loaded would be quite problematic.

I do.
Some pass through the resizer with no effort, some take quite a bit of effort. This tells me it's best to resize.

This question comes up often. Is it really all that time consuming to run the brass through the sizing die? You are at the press anyway to load so why not run them through? New brass is shipped and packed and put on the shelf and dropped and ..., you get it, right? I send new brass through the sizing die to be sure the necks are sized correctly and any dings that might be in the case mouth are ironed out. It will take you longer to post and read this thread than to size the brass, especially since it's straight walled 45-70 brass.

I guess he doesn't want to run it through if he doesn't have to. Maybe he's tired. Maybe he has a sore shoulder. No offense, Just sayin'
I just got some new 7.62x54 brass that I didn't resize first. I did do some quick measurements and found the factory brass to have round necks, shorter then needed trim length and plenty of shoulder set back. After 2 firings it's still to short to trim. My take on new brass is get it loaded and get it shot so it can be resized the way I want it.

Some years ago, i'd picked up a batch of new brass for a varmint rifle. spot checked several rounds for length and found several over the max AOL. Since then i've just made it habit to size and trim if needed.

I always do even with new brass.

New brass always gets sized, trimmed, flash holes deburred, primer pockets uniformed. That way you know it is all the same, just keeps it consistant.

I do, just cuz cases can get banged & dented.

No, not necessary unless the neck is "dinged", and then all you need to do is run the expander ball thru the neck to straighten it out.

I always run my new brass through the sizing die and process them with chamfers, even the Lapua brand, which is as good as it gets, IMO. I always believe that consistency breeds accuracy, and any steps that u take to gain that consistency is worth the extra time. If your neck tension varies, it can affect your groups.
I don't worry about the time consumed at the reloading bench, because it's all good.

Is it necessary to post the same question on multiple forums at the same time?

Wow, That's some detective work there.

About a year ago I was running through a large batch of 223 brass. It was new Lake City "11" brass. After about 850-900 sized pcs I got lazy and just measured the remaining 100 or so to check for a trim. The ones that were too long got trimmed but none got ran through the sizer. I kept them separate.
After loading a nothing fancy H335 and 55 FMJ plinker load, I noticed they were less accurate than the exact same loads that were sized. There were a few with 'out of round' necks that I used the boat tail to straighten out. Not the worst result but I guess worse things could happen dependant on the cartridge.
All that said... Take the time to size them. Shortcuts cause problems.

If you have to ask...then you must have some reason to think it might be a good idea. And you're right.
I resize all new brass except low pressure handgun brass. Come to think of it, I've never had any brand new low-pressure handgun brass.

I would definitely tumble and resize any new brass, ever, period.
Once upon a time I bought some primed 7.62x54R brass from Midway. It was brand new. I assumed it was safe to just load and shoot, so that's what I did. Several misfires and stuck bullets later, I realized that there was still lube inside the cases that was contaminating my powder.
Since then, I trust no one. I assume all brass needs the full treatment.
I've done that before.
There might be someone who is the most knowledgeable guy ever who doesn't frequent THR.

I have had 357 mag, 45acp, and 45 colt brass that without resizing you could push the bullet in the case by hand then turn it over and dump it out. So, yes, in my opinion, new brass should be resized.
