Does anybody know what Remington 700 models are using the 5r rifling? Are they all stainless steel barrels? It seems like I read somewhere the VTR you could get in 5r rifling as well, Remington was using it on more than just their mil spec sniper rifles. Any info if the rifling is any better or is that just marketing or an old wives tale. Any info even somewhat related to this is much appreciated.
