There is a difference in the rifle being capable of 1" or smaller groups.....and the operator being able to consistently shoot up to the capability of the rifle. Indeed, there is variability in this, no matter how practiced the rifleman, or how good the equipment. If one has a 1 MOA rifle....and the ability to shoot that well...does that mean that these will be the results ALL of the time (let alone , MOST of the time) ? I think not. Every one of us has "off" days.

I don't consider having a 1 MOA rifle to be such a huge technological leap - I have an old military Mauser-type rifle that, since being glass-bedded and free-floated, is certainly capable of 1" or smaller groups. I have achieved this, with handloaded ammunition. However, can I say that I am able to duplicate this performance - consistently ? Certainly, NO. I am SOMETIMES able to get this kind of accuracy - but certainly NOT all of the time.
