I think it's all down to ammunition and ballastics, a 270 packs greater grain bullet and velocity than both 243 and 308, I had a rem 308 which I swapped for the 243, and to be honest I should have kept the 308, but choice of rounds and price led me to 243, I've since had use of a 270 on occasions, which is why I want to move up. There are other factors too, friend reloads 270 for peanuts and the federal ballastics are great. I was just wanting to know if stainless had any better justification for more than double the price.
I do appreciate your input though, thank you.
