Just keep in mind that "MOA" seems to have different definition depending on who you talk to.
When I say 1 MOA I mean that with the chosen ammunition will shoot 5-10 shot groups into 1.042 inches at 100 yards, day in and day out with no 'called shots' or 'flyers'.
The reality is that many people describe a guns as 1 MOA because it has done it on one occasion or another. The reality is that there aren't very many true, consistent production 1 MOA rifles. And those that can shoot 1 MOA invariably do so with a particular loading.
Keep in mind that most military ammunition is only capable of 2 MOA or worse, so no matter what rifle you use, the groups can never be better than the most poorly performing component. If someone tell you their rifle shoots MOA with surplus Chinese 7.62x39, you should be dubious, since testing by the US Army showed at typical variation within lots of 4.6 MOA.
Not that the US was much better. Many early M14 rifles were unable to meet the Army's 5.5 MOA acceptance standard (Yes, 5.5 MOA - Look it up), primarily do to ammunition.
Thankfully, ammunition both commercial and military is much better. But even commercial ammunition has enough variability that makers either load special match ammo, or in the case of rounds like 6.5 Creedmoor, create who new cartridges specifically to sell commercial ammunition to match shooters who don't reload.
BTW, if you go to precision rifle matches, see how many are shooting commercial ammo. The vast majority don't, because the precision of the ammunition is the limiting factor in the system. Big makers can't afford to weigh and sort brass, weight every bullet and powder charge and still sell at a price point people will accept.
