[QUOTE="vancewalker007, post: 2334743, member: 66917"] Both cartridges will perform very close to say 1000 yards using high BC bullets like a Berger 156 EOL and a Berger 180 VLD Hunting and 26 inch barrels and hand loads. One of the advantages of the 7 Rem is it will be a better travel rifle because ammo for it will generally be available almost anywhere. One of the big advantages of the short mag is a lot less recoil and being able to fit into a smaller package. Typically longer mags will be a little less efficient than short mags in shorter barrels. So if you want to use say a 20 or 22 inch barrel look closely at the drop in performance between the 2. I know the 6.5 PRC will be about 20-25fps loss for each inch of barrel removed. So my 26in load that runs 3040fps from my 26 drops to about 2940ish in my 22in. There is some published data on this for the 7 Rem on the web I believe. This may put the performance advantage in the 6.5s favor. Either way if you are getting a custom chamber get the chamber cut to give you as much powder capacity as possible. This will give a little more favorable internal ballistics over the SAAMI standard. [/QUOTE]
