I have used a LOT of R17 in my 6.5-284s. I am only getting about 500 rounds out of a barrel with it. Won't try it in my new 6x47.
Are you thinking RL-17 burns barrels faster than other powders?

Yes, it is hard on barrels- much harder than H4350, 4831, Retumbo, H1000- I could go on. For a hunter that doesn't shoot more than 40 rounds a year it is wonderful stuff. For a guy who shoots a couple of hundred rounds a year he will be buying barrels.
