I believe that 6.5-284s wear out quickly for two main reasons. One is quite a bit of powder down a small hole. The other is that is has historically been a competition cartridge where people run it at _high_ pressures and need a replacement when they lose a couple to few tenths of precision at distance. Run it at 6.5-284 Norma pressure limits, and use it as a purely hunting rifle, and I believe you’ll get well more than your desired minimum life out of a barrel.
