Yep. All 4 in my safe will do MOA with hunting bullets..
To the OP - I'd also consider a plain Jain Montana. My 270 84L weighs 6.5 lbs with scope, my 308 a bit over 6. It's up to you on $ spent vs how many ounces to save.
I also agree with your cartridge choice. I've been a fan of the 280 since the early 80s. Tough to beat a good 150-160 gr 0.284 bullet. I will say, in a light rifle, the 280 is going to recoil a bit.
