Let's forget barrel life within reason.. Let's face it this isn't a money making hobby. We are in it for fun! I am thinking a rifle for the dogs out there 800 to 1200 yards per say. I get a bigger kick out of those than the close ones. It will only get 150 rounds or so per year. What do you think the pure velocity I thought 6x284 for splat factor and just a 284 for ballistics but I question if speed might be king on the dog field as distances change and you may not notice. What loots like a few yards is actually more like fifty. Let hear your thoughts.
