[QUOTE="jbur13, post: 2768217, member: 74423"] exactly. The PRC can shoot heavier bullets that will stabilize in an 8twist. Standard 7RM is 9.25 and cant stabilize 180grain bullets. So, the 7RM shoots lighter bullets, 150g (factory ammo) at a little over 3000fps out of a 24" barrel. The PRC shoots 180's at a little over 3000fps in a 22" barrel. big difference in Energy! That is where the forums go sideways, they aren't accounting for the people who load their own ammo. I had a 20" 7RM built in an 8 twist and it shoots 175g at 2925fps. and to go back to another comment, yes, it was built to carry a suppressor. [/QUOTE]
