I am finishIng up a batch of 100 Peterson 7BR to 30BR. So far the only troubles I have encountered are the 3 pieces I bit the shoulder turning the necks. After 1 cycle fireforming, it appears to hold a grain less than my Lapua brass.

Let us know how it shoots with the brass and load data. Less powder and same or better results is always better - I think?

Will do. The first time through fireforming I was using 33.0gr of LT-32 under a 110gr V-Max. I then tried 34.0 and put 3 shots in one hole. Switched shooters and she had a 3 in one hole group and a flier, and 2 four shot groups with 4 holes. Next time out we try 35.0 grains.
Rifle was dirty, we were running out of light, wind was blowin'.... I know they are excuses, but it keeps me thinking there is something to pursue here.

The 30 BR Remington is the only one likely to find in a manual - as it is a "legit" cartridge. Berger and another manual or two of mine list that as well.
Something different with the 30 BR?
I had a reamer made with a longer throat to shoot heavier bullets. 1 in 10 twist 22" #7 profile. Have shot up to 175 gr bullets but mostly shoot 168s. It is a SA Rem 700 in a Rem laminate stock with a picatinny rail. Timney trigger. It is a repeater and feeds the cartridges very smoothly. It is lots of fun to shoot and is the test bed for any scope with an issue.
Currently using 168 Hornady match bullets with necked up 6 BR Lapua brass with IMR 8208 XBR, velocity 2490 fps.
Brass is neck turned brass so I get .001" neck tension using a RCBS FL die without sizer ball. It is very accurate and lots of fun to shoot year round.
I realize most 30 BR shooters are competitors, just thought I would share.

I abandoned the entire project. Now have a 6BR barrel chambered.How is your 30br work up going. Still waiting on that target.
I was astonished at the accuracy shooting the fire form loads. First real test coming up this weekend. I’ll post a target, I promise. I’m quite chuffed with the gun as it turned out and I think I can get it to shoot!How is your 30br work up going. Still waiting on that target.
Looks like it's beginning to come together no doubt. What bushing are you using?
324. It’s a Krieger chambered by Alex Wheeler with a .332 neck.

Almost there now. What is your next adjustment?
Well. With the vertical out I'll start with seating and then fine tune neck tension.
