338-375 Ruger Demon

2750-2800 would likely be top end with that heavy a bullet. I shot them in my 28" 338rum with rl26 and 2900+ was pretty easy to attain. My fired 338 rum brass holds 110gr water. That rifle shoots 300 Bergers very well at 2810 using N570.

I wonder if we're splitting hairs here. The 33nosler has to be around 96-98gr water capacity. I've personally measured adg 28 nos at 103, 30 nos at 101, and the 33 is a touch smaller yet. It'd essentially be the same performance wise, the prc parents just offers more brass options.
I think 2800fps with a 26" barrel with the 270 class bullet would be respectable.

I know rl26 and N565 will likely be the best for performance, N560 is great velocity wise too, but not temp stable and it's crazy dirty, should be better in the larger bore diameter.
 
Wonder how H1000 or Retumbo would do?
They both do well in a 300prc, time will tell. There are guys with long throat 33 noslers using rl26 to achieve 2900+ with 250 Bergers, so H1000/Retumbo should do mid 2800s getting close to pressure.

I was getting 2850 with 7828ssc and 250s before changing to n568
