New winchester brass, are these acceptable?

I sure hope you meant "tale" and not "tail" in your last comment. I can assure you it is no myth that old wives have tails.

Ouch!
Dang spell check even let that one past,

Donovan, those are good points. New brass is dimensionally perfect to the way they are manufactured. The thickness of the walls is as it should be for the rest of the case.

If you are unable to chamber a virgin case without F/L resizing it first, you have an issue that needs investigation.

If you can chamber it, why are you resizing it in the first place? If the case is too short, no amount of resizing will fix that.

By F/L resizing, the only thing you can do is push the shoulder back. If you adjust the die to not do that, what the heck are you resizing in the first place.

If you fire unadulterated virgin brass in your chamber, what you get is a fired case which has grown from its proper starting dimensions to the dimensions that you will get every time you fire that case in that chamber. Now you have a choice. If you want to load for optimum precision in a specific chamber, you adjust the die to bump the shoulder back a few thous, and you repeat from there. This case has been fire formed to you chamber and you keep it that way.

If you decide to resize to the SAAMI dimensions, you adjust your sizing die for that and go from there.

You have to agree that any chamber into which you will insert a virgin case has to be bigger than the case. Why do you want to make it smaller in the first place?

I understand your reasons for doing what you do. I simply said that F/L resizing virgin brass shortens its life.

The case mouths are an easy fix but the flash holes are usually off center or oblong....the quality just isn't there.

I have had horrible luck with new Win 308 brass lately. The last batch I received the case head measured .463-464". It was barely big enough for my extractor to grab. I called Olin/Win and they sent me UPS shipping label to return it to them for them to inspect and replace. Still waiting. I've called a couple times and they are still processing my request. I think when/if they send me new brass to replace mine, I'm going to sell it and replace all of it with Lapua. I've already started using Lapua and the way it looks, I'm not going to quit. Lapua's quality is by far on another level.

How can you quantify that? Just bias experience?

If so, my experience is almost opposite, F/L sizing new brass has no effect on brass life. Trouble is every loader experiences brass life in a different manner because of load, rifle chamber, die type, size and maker, sizing technique and other variables.

I mean if you actually have any kind of scientific or metallurgical data to back the claim as to why sizing in this new from manufacturer state shortens brass life I'd like to see it.

Coffee with Bubba and Clem at the range after a shoot doesn't count as data.

I was in Kansas about 30 yrs ago and was talking with some of the locals. One asked where I was from and I said Texas.
He said, I thought so.
I asked what made that so obvious to him.
He said,"You can always tell a Texan............but you can't tell him much"
I didn't think he was right then, but now 30 years later, I stand corrected.

I see. So when you lose the argument you start flinging insults. Nice place you got here.

I just recieved the 200 new Winchester brass I ordered Monday. When I inspected them to prep for loading I found that 35 have either flat spots on the mouths or they were not round, also two had cracks in the necks. I'm afraid to open the other bag.

Hey Justin,
There are several opinions here and I hope your question was answered ok. This thread has turned out not so well and if it were me, I would just delete it and move on to the next one. I hope you don't think all threads are like this one, because it very seldom happens on this site. I wish you luck with your brass. Nice pictures BTW, very clear for as close up as they are.

Hey Bill, just saw you on another post.

 

[Nomad47]

I hope I was agreeing with you.

Nobody has lost anything, and for what it's worth I'm not arguing. I simply asked for relevant data beyond opinion.

I have never seen anyone else make the kind of statement about brass that equates F/L sizing before the first firing causing brass to wear-out faster.

I F/L new brass because I want all the brass to be in as similar condition as possible when the selection process begins
