If you want to use a 6.5 for high volume varmint shooting, you would be best served to back way off on case capacity to the 6.5x47, .260. 6.5 Creedmoor, or 6.5x55 to get longer barrel life.
Of these, the only one I own and have shot is the 6.5x55, but I have not used it for high volume shooting. I like it better than the 6.5-284 NORMA, which I also have. For an everyday cartridge, I think there is a lot to be said for the 6.5x55/.260/Creedmoor/6.5x47 class of cartridges.
If more performance is desired, my preference is to skip the 6.5-284 and proceed directly to cartridges in the .264 Win Mag class. Some folks will claim that the 6.5-284 is in that class. My experience with my rifles says they are all wet. If you step up from the 6.5x55, you have to be prepared to pay a significant price in barrel life. It costs more to go fast. That's just the way it is.
