260 rem pressures

2900+ with a 140 in a .260 is a STOUT load!

I don't think you're in Nuke territory, but I'd suspect brass life will be short.

Personally, I'd be backing it off a bit.
I was thinking of creeping up to 3k just kind of in my foolish dna I guess. I've got 55 left at 2900 so that should make it thru deer season if I use it. I've gotta try it on a deer to see what all the hype is. I'm usually a 22or 6mm fan for deer
 
Here's a .260 running 143s at 2850. Load was "fine", until it wasn't. Re17 in Rem brass, lucky we found all the parts and the hunt was able to continue.
