As someone who have been in this game longer than I have been alive, you should understand that there is a huge difference between a rifle/ammo combination that is capable of sub-MOA performance versus the same for a rifle system (rifle, ammo, scope, bipod/rest, shooter, etc.). The original poster was somewhat puzzled why his system seemed incapable of such performance.

I've already proven on multiple occasions that my rifles are capable of such performance as long as the rest of the system cooperate. This includes my ability to read the wind and break the shot without disturbing my sight picture. Back when I was reloading my own ammo and shooting at least 200-rounds every weekend, my Savage 110FP Tactical, housed in a Choate "Utlimate Sniper" stock, using a Harris 6-9" BR bipod, topped with an SWFA 10x42M scope; I would consistently print 3 and 5-shot groups that hovered around .75 MOA. I was also capable of calling my shots back then.
