[QUOTE="3006savage, post: 216421, member: 12069"] Several posts referenced the 7mm Rem as having a bigger capacity. The case capacities are actually equal. The 7mm Rem is 83.2 and 7WSM is 83 grains. If you reload I would choose the 7WSM for the following reasons. 1. Shorter case provided more efficiency with equal powder. 2. Shorter case provides more consistent velocity which at long range improves accuracy. This has been well documented in benchrest competition shooting. 3. Unbelted case headspaces more positively on the shoulder for better accuracy. 4. Shorter WSM case allows for lighter actioned rifles which in turn allows a lighter carrying gun or heavier barrel contour for reduced barrel whip. 5. The 7WSM ballistically outperforms the 7Rem Mag at all weight bullets. For instance the Federal Cartridge 160 grain NP is listed at 3160FPS this is a pretty heavy round and it is 100+ FPS beyond any 7mm Rem Mag factory loads. If you do not reload the 7mm Rem is the ticket due to availability. [/QUOTE]
