For me, the biggest difference between the two is the 6.5 PRC can be run in a short action and a Rem 7mm mag needs a long action.
That's great info. I run a 6.5 PRC in a SA, and am limited to bullet selection because of this. SO if your looking for max range high BC and energy, your 7 will out perform the 6.5 PRC.
IF you don't reload then you're limited even more with the PRC regarding load selection, and if you do, you get an even bigger advantage with the BC of the 7 because of the better selection of bullets.
