6.5x284 is the cartridge to beat at 1K yards for a target shooter, at least in prone competition. It's a barrel burning SOB that has nothing on any decent hunting cartridge at 500 yards and under.
The brass is expensive and my barrels were replaced in less than 1000 rounds and usually at 800. When and if I ever get to competing again, I'll go with the 30 cal.

When people face the possibility of freezing or starving there is little chance they are going to listen to unfounded claims of climate doomsday from a bunch of ultra-rich yacht sailing private jet-setting carbon-spewing hypocrite elites
