Nit implying this is your problem 338 but from my findings the below is where it starts!
Dare I say it but powder really shows its temp sensitivity at high pressure!
Dropping your load back below max things often settle down alot!! A hell of alot!
2225 goes very well in an edge as long as you keep your load at good safe working pressures!
IMHO
94gns is a good safe 2225 load to sit on !!("workup") it can and will shoot up as far as 96 or even 97 but its teetering on an "EDGE" of brass life an pressure spikes!
I still have a pile of ruined brass from a pet load givin to me sitting in a box from 2225!
94gn N570 is a fantastic load for an edge well below max and 40fps up on 2225 at any stage of matching pressure signs!
