What does a load that the rifle doesn't shoot as well have to do with anything? That doesn't even make sense. That's WHY we handload, sort brass, neck turn, check runout, buy expensive dies....
OF COURSE, the rifle doesn't shoot any round you put in it to less than MOA.
If that were the qualification for a sub-MOA rifle, there wouldn't be a single one in existence.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
