[QUOTE="J E Custom, post: 1252821, member: 2736"] I was surprised by the listed velocities differences also when I first started researching the two cartridges and found out that the data for the 6.8 that was being compared to the Creedmoor with a 24" barrel and the Remington was for the 16" barrel length, and the 20" barrel would produce the velocity Remington ammo advertised. (They designed the 6.8 and developed it for a 20 to 22 " barrel). I did find out that Remington does make ammo in a lower velocity (The UMC brand velocity is 2625 ft/sec for 1759 ft/lbs that still has 250 ft/lbs more energy that the best Creedmoor load)unlike there premium ammo. My 6.8 AR has a 22" barrel and will duplicate the listed velocities. And In my bolt action rifle that carries a 23" barrel, it will exceed the listed velocity of 2800 by 31 ft/sec (It has a premium hand lapped stainless barrel and that could account for some of the velocity increase) but it does great with the Remington ammo and also with the slower Hornady (2460 Ft/sec listed, and actual velocity is 2610 average) I have not been able to match the factory ammo velocities with reloads by an average of 35 ft/sec, probably because the factory loadings are proprietary use proprietary powders. (Common in many factory ammo's) Alexander Arms (The designer of the Creedmoor) really took liberties with there posted velocities of the 6.8 and even loaded ammo for a while that would not even match the Creedmoor velocities to make there cartridge look better. Its a shame, because the Creedmoor is a great cartridge and needs no help by posting false information on its competitors. I wanted the rifle for Hog hunting and went with the most power between the two and have been pleased. J E CUSTOM [/QUOTE]
