Based off of what I've seen with my 270 STW.
Barrel life will be short.
Toasting the throat doesnt necessarily mean that it will loose accuracy.At least not right away. But what typically happens first, is you loose speed.Would not surprise me one bit if after you got to 300 rounds that you drop 100 fps due to "throat roast".
Thinking this would be a good application for Melonite barrel treatment.
I got a look at the reamer print today.The 26 has a 35 degree shoulder.and looks like a nice clean looking round with no surprises.
For a open country,flat shooting,hard hitting, low recoiling round.Id carry one..
I hope Nosler does well with it.
Run a 127g Barnes LRX at 3450 fps.
And poop will die...before they hit the ground....

Only accurate rifles are interesting.
