I think you have two types of barrel life with the 6.5x284. You have the 1000yd match rifle here is something I copied from another site, "Barrel life is a key issue for 6.5-284 shooters, because barrels can loose their accuracy edge in as little as 800 rounds, though 1000 rounds is more typical. But don't throw away that barrel merely because the groups start opening up. Sometimes some aggressive throat polishing can restore much of the accuracy, and you can get hundreds more rounds of useful life by having the barrel set back.John Hoover reports: "I've had many barrels set back 1". Nearly always they shoot as well or better than before."
I think a match 6.5x284 might be loaded alittle more aggresive that I would load for my 6.5x284 so if your only shooting 100/200 rds a years as a LR yoter/antelope rifle you my get better barrel life. My 6.5x284 was build on a long action.
Well good luck
