[QUOTE="Michael Eichele, post: 901199, member: 1007"] Equal bullet weights and equal form factors, smaller calibers win. You're right there. Maximum potential always goes to a bigger caliber. Comparing the 260, 708, 308, they all have equal windage abilities. Apples to apples lets use the 140 amax, 162 amax and 208 amax at realistic velocities. 2750, 2700 and 2600. Using published BCs which are close (at least to 600 yards, all a but less at 1000), you'll see that the windage is nearly identical. The energy goes up as the caliber gets bigger. The trajectory between the 260 and 308 is only 20" different at 1k. If all you cared about was trajectory, you can run 155 grain pills at 3000'sec in the 30 version which a 260 can't touch until you drop to 120s. Again though, the recoil goes up with the bigger bore but so does the down range performance. Barrel life goes up as well. Barrel life for me is more important than some added energy. I do a lot of shooting and grow tired of cooking my trusted and sweet barrels. [/QUOTE]
