I want to replace the plastic stock on my Rem. 700 7mm mag.. I was thinking of an A3 style, but was wondering if that would limit the practicality of the rifle. I shoot it prone alot and off the bench and maybe at closer ranges while utilizing a tree for a rest while in the timber. Heck, mabe even off hand. How do the A3 styles work for you guy's in non prone situations? I'm looking at Russo's for laminated wood or Manners in composite.
