140g Bergers vld hunting bullets are better suited for a 7/08. The 140g Nosler Combined technology bullets never detonated on the surface, and we never killed deer under 75 yards with them, from 7 Mag at 3250 to 7 STW at 3650. Having said that, the Nosler 150g Ballistic tips are a very different animal vs the 140g, they seem to be much tougher or penetrate better on quartering shots. 120g and 140s is what we shot in our 7 STW's.
So, the 7 PRC has almost identical case capacity of the 7 Rem mag. If you had a reamer set up to shoot 120-140g bullets(standard Rem 7 Mag SAAMI .110 freebore works just fine), you should expect exceptional accuracy, just like the 7 Rem Mag achieves. However, we found in all of our 7mm that the 120 and 140g Noslers shot very, very tiny bug holes when they were seated to just barely touch the lands or .003 off the lands. So, jumping the noslers, is NOT part of our family's way of doing things. We get 2.5-3.5" groups at 600 yards with the Rem 7 mags that have been bedded, freefloated, with muzzle break, 6-24 scopes, we have our own 700 yard rifle range.
