at my age of 66 i don`t think i would burn a barrel out of a 26 Nosler or a 6.5 -300 Weatherby ,both of my 264 Win. Mags and all my 257 Weatherby`s still have plenty life left in the barrels . once i have the hand loads developed and the rifles sighted in ,i only use them for hunting ,maybe a couple of shots before the season to make sure the rifles are still sighted in.besides wiping a rifle down a little i may clean the bore of the rifle every 4 or 5 years , cleaning rifle barrels is way over rated for a hunting rifle.
