I've been considering the GSR for some time now, for many of the same reasons as you Gary. Ever since I gave my trusty 18" Sako "Handy" in .308 to my son in law for Christmas, I have been lacking a .308 bolt gun.
My question that hasn't been addressed by the magazines is how does it carry in the hand? Where is the balance point if you want to grab it up at the middle and go for a walk? Have you seen the 5 rounder and does it fit close to flush for an easier carry when hunting? And last is it set up with sling options that would accomadate a patrol carry or maybe a ching sling.
