I know ADG vs. Nosler in .300WM has a 14gr difference in brass content, and a couple grains less case capacity in the ones I have used. But that means less charge weight for the same pressure. I got surprisingly higher velocities with same charge weights in both cases.
Same in my .300RUM.
But the brass is absolutely awesome. I would expect 28 Nosler to be the same.

Please clarify.
How does less capacity equal higher velocity? I understand less case capacity with the same amount of powder equals higher pressure, but all cartridges have a limit. Larger case capacity leads to a higher amount of powder to reach max pressure, thus more gas propellant = higher velocities.
Please disregard if I misunderstood your post.

Exactly. Less case capacity with the same powder charge equals higher pressure and therefore velocity. I have seen 83.0gr of RL33 in one type of brass have the same velocity of 89.0gr of RL33 in another type of brass across several rifles. And even in the same rifle.
My .300RUM needs 4gr less powder in ADG brass than Nosler brass to reach 3110fps pushing a 230 Hybrid. And the ADG brass is much higher quality and handles the pressure much better.
UGH, I'm on the, hurry up and wait list.
I took one nosler and one ADG brass, put a spent primer in each.
Loaded each with H335 powder using a 6" drop tube.
The nosler volume averaged 109.1 grains
The ADG volume averaged 112.2 grains
I weighed 50 ADG brass,
260-260.9....5 total
261-261.9....37 total
262-262.9....8 total

With the ADG brass being lighter than Nosler, the ADG brass is likely to have a greater capacity.
I sure would like to know how many grains of water the ADG brass can hold!
8andbait... have you loaded and shot the ADG yet?
Looking forward to any comments on the ADG 28N brass.
Okay, what we need to know now is, how ADG handles the 28 Nosler pressures and what the max usable powder weights for given powders are?!
I found 2 accurate velocity nodes with Nosler/Retumbo/180 ELDM
1st 80.4gr 3146fps avg 6.8 SD 15 ES brass is still re-loadable
2nd 81.6gr 3195fps avg 6.2 SD 16 ES brass is toast
I want that 2nd node if I can get it?!

Expand like the Grand Canyon! I felt it when I deprimed a new batch after the first load tests, 12 of them kind of just came out without much coaxing and you could prime with your finger
I was expecting the primer pockets to hold up better than Nosler. How does that compare to Nosler 28N primer pockets?
