Those are brute strength verses pin point accuracy. Now don't get me wrong... the 243 is very capable of excellent accuracy, it's just that these are proven in the competition world. If you you use the Dasher, BRX, and their derivatives of ackley type shoulders, the velocity is really not that much slower until you jump to the 243 AI, but then barrel life suffers. You get 3000rnds with a Dasher, and 1200-1500rnds with the 243 AI. Guys are setting up Varmint rifles in these calibers because they are better suited for hitting tiny targets way out there. The other is powder costs. You can load a Dasher with a max of 31+ grains. The 243AI loads to 46+ grains. So your pound of powder will last you longer.
So I guess it boils down to, barrel life, accuracy, and reloading costs. I know what I want and that is cheaper accuracy IMHO. I don't have the money to buy a barrel every 1200rnds and if I can stretch a pound of powder and still maintain the best accuracy with little loss in ballistics, that is the route i will go. It all depends on what a guy wants.
