30BR

I tried these as well with 30.0 Gr. AA-LT-30 and CCI BR-4. My 5 shot group was .338 Probably won't bother with them again.

I'd be surprised if they won't do quite a bit better with more testing and maybe a more appropriate load. Yours seems pretty light and it's just one group. I wouldn't judge any bullet by a single group. As with anything, more testing will show more data. Your barrel may never shoot them well but for $24/100, if you can find them, they are surprisingly good. As I said in the previous post, I don't compete with them because I don't trust them to be competitive with customs through a 1 or 2 yardage agg. But I've seen them shoot well enough to do in a pinch. I'd add some powder to that load. It's likely about 4 or 5 grains light. A load that far off that still shot in the low .3s might just have potential but yes, it's got a long way to go.

Yea, AA load data show 31.9 as MAX for the 125 Sierra with a bearing surface .391 and the 125 Speer's bearing surface is .287 so it could stand more powder.

I'm not advocating for loading dangerously hot but I'm not sure anybody at a match is loading by book data. You have to do what is within you ability to read pressures and what you are comfortable with. But hell, I dont think I have even seen a 30 br in a Reloading manual before. I've got maybe a dozen but they' range in age from 5 or 6years to about 20 years old.
It's still a wildcat so I kinda figure that you're on your own anyway, as there are no saami chamber or pressure specs, that I'm aware of. I'm speaking purely from experience, not what I've read online or in a manual. Ymmv.

Accurate Arms & Sierra have the 30BR listed in their manuals but I have not seen it anywhere else.

Sierra list bullet weights from 110 gr. to 190 gr. in their VI Edition.

Fascinating. Exactly where I landed. Using 115 Berger’s for lack of anything better. I’m to shoot tomorrow again to confirm the charge. I’ll try and post a pic of the target.

My first 30br barrel. Shooting it on my 10.5 lv. The more I shoot it the better I am getting with gin handling. I am going to add some weight to the stock and may add a heavier scope to balance the gun. Surprisingly, it handles pretty good to be muzzle heavy.
 
Anyone using 7BR cases to form 30BR cases instead of using 6Norma BR cases? Pros and Cons either way. I was wondering if the 7BR cases held more H2O. Petersen makes the 7BR cases.

I hope they are, and having great results.
I have 100 pieces of Peterson 7BR that I am planning on making into 30BR.
It should be as easy as expand the neck, turn, and shoot.
 
Make sure you use a LOT of lube when expanding the 7BR! I crushed 4 of the 50 I expanded up to 30. Vs splitting only 1 of the 100 Lapua brass I expanded to 30 with multi steps.
You will find that the 7br brass is shorter spec wise to start, thus the finished case will be shorter then your might like for you chamber length.
I never fired the 7br brass so I can't give you any information on longevity or performance.
