Everybody expects then to shoot 1/2 MOA, but they just aren't capable of it. A match-tuned M14 done up by an armorer who knows what he's doing is a 1MOA rifle. That's 10 groups of 10 shots each. Not a single 5 shot group, which is what everybody puts out there as an example.
I got the best groups from mine with 45 grains of W748.

1 moa for how long , is that not the challenge with m1a/M14
what bullet are you using? 45gn of 748 seems very warm for M1a ? I think what a lot of folks dont see is how quick the pressures can rise even with a simple bullet profile change.
I know there are a lot of "go to" loads for M1a, M1 ARs ect ect. that work just fine.
