Surely, facts can be backed up by empirical data that shows that the Remington 700 is more accurate than any other production rifle in the world. I'm sure we all would be most interested to see that data. Personally I've shot more than one European rifle that would keep three shots in one ragged hole at 100m any time I've done my part and I don't consider myself a great shot. My 30 year old Ruger 77 6mm will do so as well. The AR-15 platform is consistently outshooting almost every other platform in competitions. The Savage F-Class rifle is supposed to be outstandingly accurate. The Steyr tactical rifles as well as the Blaser tactical rifles are quite well known for their capabilities around the world.
I'm not sure that there has ever been a shootoff of all the worlds brands, models, action types and chamberings. Until such time, no one will ever know what is factually the world's most accurate rifle. Until such time everything else is simply opinion. You might be able to get away with the most accurate sub-$600, American made, bolt action rifle; but then again on any given day you might get beat by a Savage...
Strangely enough... my 700 SS will only shoot about 1.5 inches or so. Of course I'm not a reloader. I'm sure a reloader would be able to get this down to world class accuracy in the .3's or so.
My Tikka T3 will shoot under an inch with the only load I have ever shot in it, Federal Power-Shock 150's.
