[QUOTE="TriggerTime426, post: 2790404, member: 113663"] If I remember right they developed the 7mm prc to be more efficient in shorter barrels than say a 7 mag, 28 nosler, 300 mag etc. With sharp shoulder, shorter but fatter case. 180 class bullets would be goin at least 2800fps even with the 22" barrel, and that would be at least a 800yd setup depending on accuracy....idk if you really gain a whole lot of mobility by goin to a 20" barrel especially in a 280ai unless your using a suppressor, I think goin with a 22" would benefit u more in performance than 20" would in mobility....also why not build 2 7mm prc's unless u have 2 different bolt faces already just curious.
