Someone on here mentioned that there wasn't much difference between the 6.5 & 7PRC but by my calculations theres over a 25% increase according to their H2O capacity

6.5CM - 52.5, 6.5 PRC - 62.0, 7mm PRC - 78.0 & 7mm RM 82.0

All factory Hornady "precision" ammo apart from the 6.5PRC ( but similar to factory )




PS - Just a couple of observations, I'm on the fence with the 6.5 PRC, I've had a couple & I love the cartridge, it's great fun to shoot but not sold on it's killing performance & while I still like the Rem mag, down side being a magnum the projectile in factory ammo are seated very deep to mag fit, something that modern cartridges seem to have improved on.

The 6.5 PRC cases Iv weighed have held 68gr H20. The norma and Lapua 6.5x284 hold the same 68gr + or - a point , hence my opinion the that a wildcat 7mm/ 6.5 PRC would be a waste of time when a standard 284w will be its ballistic twin . Also makes me wonder why the 6.5 PRC even came to be when its just a slightly fatter 6.5x284 and only .12" shorter.
The 7mm PRC is a different beast as you stated.
