Bit heavy for a 223
The reason is people shoot a 3 round group, have one tight group and claim it shoots 1 MOA. They say the rest of the groups were poor because of a flyer or wind or whatever cognitive dissonance they can think of.
If you want to read an excellent write up about it.

Oh, I get all that. But telling us that the accuracy wasn't as good because they shot 5 shot groups and not 3 shot groups? If it's a 3 MOA gun, just tell us it's a 3 MOA gun. The 5 shot groups tell us more than 3 shot groups about the accuracy potential of the rifle - yes, definately. But 3 shot or 5 shot is not an excuse for a lack of accuracy. Heck, why don't we just go to 1 shot groups and every rifle will be MOA.
Barrel break-in. This may affect your accuracy. I've read it all, and I'm still not sure I believe it - but that's just me. Light bullets in a tight twist - yep, that may affect accuracy. (although this is more an issue with heavy bullets in a slower twist. I'm not sure about "overspinning" the bullet - but again that's just me) Using cheap bulk ammo, instead of match grade - definately. But when talking about accuracy 3 or 5 rounds shouldn't make a difference if you are being honest. personally I use 5 rounds minimum. And try to do at least 5 groups so that I'm confident in my results.
My wife calls me a pessimist. I claim I'm a realist. But I'm probably just an a$$hole with an attitude problem.
From our testing the rifle is 2moa, your mileage may vary depending on ammo used. American eagle printed larger groups than ppu for example even though both were 55gr.
