I would make sure you back off your standard load and redo load development before using it. I checked them for weight last night. They are in the 131.5-132.8 grain range. Whereas lapua is in the 123-128 range. So its likely a slightly smaller interior dimension.

The good news is, out of my 200 cases I ordered, 198 were within 1.1 grains. The two left over were .1 and .2 grains lighter making the spread 1.3 grains overall. OAL of the ten or so I measured were within +- .001"

I got mine yesterday. Opened the Graf's box and took a cursory once over look at the brass. I like the packaging; the cost is reasonable considering you get the plastic 50-round hinge-top box with it.
There is a label affixed to the box that cautions to back down and rework your load and your weights would make that caution valid for sure.

I'll sit this one out! Want you guys to do the testing. First are the primer pockets holding up. Good luck.

I am taking 10 round loaded .5 under my load for 107 moly to the range Thursday. Will see how they check out. I was not shooting max load to start with. Perk

I ran a bit of mine thru the scale, calipers and tube mic. The fifteen I weighed came in within .75 grain of each other and, as noted above weigh heavier than Lapua. First thing I noticed when I opened the nice hinge-top plastic ammo boxes it shipped it was the chamfer was already done.
Measuring OD necks were all .2655-.266" (that is as good as my cheap calipers will do) and neck wall thickness, again with my less than perfect measuring skills, ran .0128-.013 with most having the perfect .013 all the way around.

For the price that Peterson charges you would definitely expect not to get that kind of piss poor product. They are right there with Alpha and Lapua with prices. What’s in the picture looks like some rejects that were picked off the shop floor by the janitor and thrown into the “good to go “ bin by accident. First run or not that shouldn’t have made it out the door.

Curious what picture you're looking at ? And what "piss poor product" you got?

Thanks goes out to @mikeeg02 for sharing his dimension specifics to his Lot of the Peterson - 6mmBR Norma cases.
Here is a case dimension blue print with his measurements:
