Case head separation due to FL resizing brass?

[WalksLikeADeer]

I'm not sure how you are annealing your brass since you didn't say or what your powder and charge is, or barrel length, or COAL, but it seems to me 2920 for 175gr is pretty hot and case head separation IS a pressure sign?

Is it really worth a a few fps to be so close to the edge when all you have to do is dial a click or 2 more? Just a thought...
