the most accurate rifle would be a custom rilfe hand built by a professional gunsmith using all the best parts made to fit you like a glove in the caliber you want...no factory rifle can compare...if u can shoot your gun out to 700yds why change?? the caliber can do it..and if you can your set...why get a VS?? 700yds is a pretty far shot on deer...if you can take them that far with a foactory rifle your a pretty bad dude in my book...
