Just picked up some 300 Win mag brass. I choose the Winchester brand over Nosler or Hornady. It was cheaper and I am cheap. So I run them through the die , just to make the necks round and then started to champher the necks to debur. 12 out of the 50 are throw aways. This is just not right. I will be using the top brands from now on and I think I will be saving money doing so. For long range accuracy the neck tension is the most important for the velosity spread.
Why were they throw aways? Your giving WB a heart attack.

That would show it the best. Smashed in dents that look like something like a chisel hit the side and it goes to the inside so you can see and feel it when you deburr. My dies are over 20 years old and have been used without this problem. I don't know what would have done this, but the brass was new in the sealed bag and nothing looked damaged on the bag. They are basically split necks on those 12. The rest look very good but still have a few small dings on some of the bodies. What happened to the good old days when they came 20 to a box with the lot number stamped on the lid.
I had a similar problem once

I took my die and brass to the HHC. Blake took one look and pointed out a crack in the carbide ring. swapped out the die and no problems.
Sounds like die/lube issues.

I don't know about firearm brass but in the water

business historically we have used tons and tons of brass fittings. They reticently outlawed it. We had a short time to install existing stores then a drop dead date on any lead containing brass fixtures.
The mix for manufacturing brass in the water industry is basically 60% copper, 35% zinc and 5% lead. They dropped the lead and substituted bismuth or a combination of bismuth and tin. It is a workable substitution but did adversely effect the cost, machining ability, and malleability. Our fittings basically went up 20% which will ultimately be passed on to consumers through increased rates. Although it may take several years.
Obama basically shut down the last lead smelter in the US and with these changes in the brass industry, in general, it would not surprise me if the ammo manufacturers were hit also. Perhaps someone can bend the ear of a technician who might actually know something. I bet it's not a widely know regulation or change.
I had a similar problem

22 Hornet brass Winchester in the bag. The necks split on first sizing, or if not on sizing, split on first firing. Called Winchester and they sent replacement brass. They didn’t care to look at the brass, didn’t want me to send it back.
Check your sizing die too, clean it and inspect, just to be sure.
Oops, this went in the wrong place

Was supposed to be in response to Asa in a post above. I shouldn’t be around computers when i have a headache.
Could be bad alloy, but I would think needed annealed?

your sizer die. Before you do anything drastic you might check that out. The last thing the die makers do before the die goes out is heat treat it and sometimes the die will shrink or expand a bit.I have never had problems with Winchester brass. Doesn't mean it can't be Winchester's problem, but worth checking out.

Sometimes too much sizing lubricant/sizing wax cause dents around the shoulder of the case. Just rezize them and you are good to go. They are safe to use. After they have been fired the dents and dimples will disappear.
Had the same problem on 223 brass years ago

Was also new in bag Winchester brass,it came out of the bag that way, the neck had almost like a channel in it, and when tried to size some would overlap and pinch.
