I don't see the 26 nos doing anything better than your 7mm, it'll recoil more too.

PRC= 6.5mm-06 or 6.5mm-284 Norma recoil levels?
xxx These numbers come from Chuck Hawks Recoil page - some look a bit off and
the PRC was not listed on his site and I didn't want to use numbers from a different one as I dont know how well they correlate to the others.
With the 26 You'll likely have to continuously tweak your loads to keep up with super fast throat erosion, and It'll be toast in 600 rounds if you're lucky!
He stated he only would shoot about 20 rounds per season... at 600 rounds that would be 30 years! If he got 1000 rounds as he doesn't shoot often enough to get the barrel excessively hot, that would be 50 years of use.

The PRC will be fun to shoot and super accurate, plus ADG brass is available.
I met a guy at a match shooting the PRC, and he was shooting 140's @ 3100 fps with H1000 from a 26" barrel.
xxx this is pretty neat! Thumbs up!
I have a 6.5 saum and its probably my favorite cartridge yet, I've taken my last three bulls with it loaded to PRC levels.
I'd have gone PRC if it'd been around when I built my saum.
