I've been eyeing the mesa myself. Lipseys has an exclusive model and theirs has the 1:8 twist. Just fyi might be worth looking into. Many gun dealers use them as a distributor so should be fairly easy to get
I don't have any browning but I've been wanting a hell's canyon. I have a couple 700s and a custom built off a 700. Love the bolt throw on the hell's canyon!
Personally me if I am buying a 28 Nosler it would be soley to shoot heavy bullets especially if you are shooting the 195 gain EOL. If I recall a 28 Nosler from a 26" barrel should push those around 3,000 fps and with a BC of .755 that would be a hell of a flat shooting rifle. I would opt for the 1 in 8 twist and not look back.
