Why would it be a can of worms? Other than a lot more recoil/velocity it would be about the same. Put a muzzle brake on it and it would kick less than the 7mm RM.
I'm having a 28 built right now. Picked up the dies and 100 rounds of 26 Nosler brass yesterday and last night necked the brass up to 28 cal and they are ready to go. I have the barrel sitting here (1 in 8 twist, 5R, #5 Krieger in bull sporter contour). The reamer is about 6 weeks out however. Nevertheless, I should have it at the range in about 3 months give or take. It will have a brake as I expect to be running in the 3,800 ft lb area which is a bit brisk if you want to be able to spot your own shots.
