Welcome to the real world. While thousands of factory issue sub-moa rifles exist on the internet I have seen few at the shooting range.
A 270 that prints 1 moa is an honest 450 yard rifle which btw is about 350 yards further than the skill of most hunters.
X2!! There are factory rifles out there that will consistently print sub moa groups, but they are the
exception, not the rule. To hear the drivel on the internet, you would think if your factory boomer does not shoot sub moa right from the get-go, there is something wrong with it. This is a fallacy that is perpetuated by the jokers who, during a range session, actually got lucky and shot
one very small group. All of a sudden, they have a sub-moa rifle!! We have it very good these days. Factory ammo is far superior to any we had in the 50's & 60's. Reloading is quite popular, unlike back a few decades, when a person who reloaded his own ammo was regarded as a bit of a dangerous "nut" who was certain to disappear in a big explosion one day.

Firearms in general are a bit more accurate than they used to be, and of course, a dedicated rifleman has a number of options to wring out more accuracy from his pet smokepole. [bedding, aftermarket triggers, barrels, etc, etc] But as 'boo observed, If one has an unaltered factory rifle that actually does shoot MOA, it is good to go farther out than at least 80% of all hunters should be shooting at game.
