Lapua 223 brasss?

[Rtheurer]

does anyone use winchester red bag 223?

Winchester brass USED to be dam good brass... And then......Not so much. I cant say specifically 223, as I use Lapua, LC, for the most part. in 308, 22-250 for 6XC, 280, it took a huge dive in quality about the time they went from Blue bag to Red bag. Primer pockets not uniform, flashholes not center and huge tag on the inside. out of a bag of 100 i would get 3 or so that the necks had this over lapping brass like a roll of Paper towels.
Just garbage.

I hope like Heck they have changed and gotten better as i dont think it could get any worse than what i had witnessed.

I’ve gotten that result using cheap box .222 ammo. Might have been PPU.

My range pick up PPU brass in my .223 with 68 Hornaday bthp Match will stack them together at 100 yards. It's a good combo for my 20" out to 575 yards. I'm running Starline 5.56 in my FTR. 223. HM scores. Edit...fat finger...

Wow, how much did .222 bullets rattle going down a .223 barrel? LOL

Variation in neck wall thickness translates to a variation in neck tension. Variations in neck tension negatively impact accuracy -period. Like Ned I have very recently inspected the neck wall thickness in various brands of brass and I have not found Starline, Winchester, Norma, Remington or Lake City to even come close to Lapua's minimal neck wall run-out. Those who find Lapua to have shorter life relative to neck splits can normally circumvent that issue with diligent annealing. Even with rifles that have tight chamber necks, where the necks must be turned, we have found that the end product with Lapua far exceeds any other brass currently available.

Not sure how brass composition became so important but here is PMI data I gathered this morning.

Peterson 6BR: 70.2Cu / 29.7Zn
Alpha 6BRA (pre-OCD I think): 69.9 Cu / 30.0 Zn
Lapua .223: 71.3 Cu / 28.7 Zn

Very useful info for me. Thank you.
This puts those three at standard C26000, Cartridge Brass alloy. And that's a good thing.
I have no idea why this information would be portrayed as a process secret by Peterson..

This depends on your context.
If the mean neck thickness of one case compared to another is different then yes it correlates to tension potential. If the mean is the same with one case consistent in thickness around the neck, while another is inconsistent, then no. Tension potential should be same there.

I don't assume anything about brass measure. I have always measured every one.
I have not seen a cut & dry trend (better/worse) in thickness variance by brand. But, I haven't used the full gamut of brands.
Actually the best I've measured, AND the very worst I've ever measured, were both in Lapua brown box 6BR, but different lots of it. The best across different lots was Norma in 223Rem, but it was too soft.
I continue to use Lapua for both of those cartridges, with no issue so far. I think it saves money overall.

I found a Norma 280 Rem case and it tested 72.1% Cu / 27.9% Zn.

Not to argue but you are kind of contradicting yourself. First you say that variation is neck wall thickness impacts accuracy and that’s why all other brands except Lapua are no good but then you are also saying that even after neck turning (so no more neck wall thickness variation) other brands didn’t come close to Lapua.
So that means it’s not just neck wall thickness variation that is affecting accuracy and there must be another reason why Lapua is better?

To be honest, when i was shooting 223 bolt guns, i couldn't tell the difference between fully prepped LC brass from the fully prepped Lapua brass..

To be honest, I firmly believe that in 223 most of us can’t shoot the difference when all brass is prepped equal.
But at same time, this is a mental game. Seeing lapua head stamp gives us confidence and there is nothing wrong with that.
