Ok, my 361 Gold Commando in unmarked stock 64 Sport Fury convertible was rare but dang it had it! Oh how I wish I had it now. Seafoam green. Dang!!!
@HalfMileKiller : my apologies for hijack.
I am on my second barrel in 30-06 AI. First was a 22" factory Ruger that was rechambered. It shot sub MOA with 180 Accubonds at 2925 with IMR 4831. It was temperature sensitive.
The current barrel is a Bartlein 26" with a SilencerCo ASR brake. With a hybrid or chimera suppressor it shoots 200 Bergers hbts at 2800 plus with sub moa accuracy with RL 23 and Staball 6.5. Reloader 23 was a compressed load so I switched to Staball. I have found Winchester brass to have 3 to 4 grains more capacity than remington or federal. It is a little inconsistent though. I also like LC brass, and have found it has about 2.5 to three grains more capacity than Remington brass. I have never used Lapua in 06.

Lapua brass gives the consistency right out of the box. The trade off is the decrease in capacity. I've always wanted to try some RWS brass I've heard that stuff is indestructible. My WIN brass fully match prepped and annealed is consistent as well, just takes quite a bit more work to get there. I have SEVERAL pounds of 6.5 SB, and it looks like I'm once again, in for more trips down the rabbit hole.

Started working up a load in the 06 AI last fall with StaBall 6.5 and 165 grain Speer bullet. Took it to 3063 with no pressure sign, used Nosler and Winchester X2 brass. Finally found some 165 Nosler BT bullets, need to load up a few and see what I can do with this bullet.

No definitive pressure signs but a very slight ejector mark on the highest hunter charge.
Accuracy was pretty good. Surprisingly small group considering the charge spread. About 1 moaish for all staball charges and maybe 1.5moa for hunter charges. 4831 was about 1moa.
I cannot speak for the .30-280AI or the Serengeti but the H2O capacity of my .30 Gibbs after the COW method using .35 Whelen brass is 73.96g and after fire-forming it from the chamber with a full load, 75.8g.
