6mm BR brass

[gunsandgunsmithing]

Seems about the same. My fouler loads are 34.5 of H4198 and a 117 gr. on the 1.00" jackets. Several pals use the Peterson 6BR and 7BR cases for their 30BR's.

That's what I want to hear, is how does it hold up to br pressures. I really have no doubt about how it will shoot but when I read how great it is and how many firings someone has on theirs, it's kinda useless without knowing how it was loaded. We all have different standards and definitions of loading hot. I'd like to see how the ARC brass holds up too. 30BR brass with h4198 has always lasted a long time as it's tough to over pressure it with h4198 and 110-118 class bullets. A small 6 at BR pressures though, I think will tell the tale of how it holds up over time and firing at reall pressures. The Lapua is a known and proven commodity and I hope the Peterson or other domestic brass will become the same. Time will tell but we just have to compare apples to apples is all. I don't really care how many firings someone gets from ARC brass at ar15 pressures but more like how does it do when 4 or 5 grains above bolt gun book data. That's a pretty extreme example but not but much at all. I don't even know what book loads are for a PPC. Lol!

that's because so many have it ingrained in there brain that you can only use lapua and nothing else.. the fan bois are going to pay the price..

Like I said above, Lapua is a known and proven product. Hopefully the Peterson or other domestic brass will be equal or better but it's yet to be seen by most of us at BR pressures. Primer pockets are the first thing to go at those pressures, typically. I have always been a Lapua "snob" but not without reason. I build guns around brass even. For ages now, it has been Lapua first and Norma a distant 2nd. Hopefully that is changing or maybe already has. Lapua is actually the cheapest brass out there, or has been, due to brass life vs all the rest...IME. But, if other brass does what you ask of it well, I see no reason not to use it. We just ask a lot of our brass in the BR game is all.

I have not seen any of the discrepancies with Peterson that you relate. I have read a few positive experiences through

Mike, we’ll really know more when I try it in my BR with 2000MR

I have two 6 BR's. In one I use lapua brass and Norma in the other. Certainly agree with you that Lapua is the best, but I find Norma not so distant a 2'nd. At least so far. JMO

That's a powder I still have never tried. Keep stuffing n135 or h322 under a 68gr bullet in there until you find real pressure. Then back off a half grain and tell me how many times you can fire a single case and still feel the primer seat. Lol!

Well, I don't see any discrepancies mentioned. Didn't mean to mention any as I have no experience with it yet. I'm curious how well it holds pressure vs Lapua is all. I hope it's as good or better!

Al, I would have used the Peterson 7BR but it is too short.
My trim to length is 1.545.

Yes....that's a good way to go. The Peterson 7BR works great for the 1.520 chambers.

I whapped my two Peterson 'fouler' cases another 3 times each today.

There's no way I'd pay more than $125-130 for Lapua 6 BR brass, definitely would go to Peterson if I needed more.
When I had my 1st 6 BR built shortly after joining this forum back in 2005, I paid $48.39/100, bought 5 more boxes shortly after that.
Bought one blue box about 5 years ago for around $100 or so.
