Accurate M1A advice

Didnt know you could build/buy a .5moa M1A. Had a Springfield Armory full on NM version, bedded, Douglas SS barrel, etc, and the best it would do was 1moa with FGMM or hand loads. Got rid of it and bought a savage 10BA-LE for the same price that shoots under .5moa. Recently built a 24" lilja barrel LR308 that will do .5 - .7 moa though (final cost was a bunch more than the M1A NM too).
 
1 moa from a off the shelf NM is good, only a MW barrel 1-11 twist. .75 moa consistantly from an M1a is doable, you need a heavy contour 1-10 twist barrel, unitized, trigger cleaned up and if your using wood it needs to be pillar bedded, barrel draw tension needs to be on the heavy side. I have shot a few .5 moa groups. This is a 6 shot group, which includes the cold bore shot, (the high hit) I was getting 100 yard zero, I shot it at member JamieD's long range school. Shot several groups like this.

 
Fulton Armory sells their "peerless" rifle. I think it's guaranteed to shoot 1 moa or better. Pretty pricey though.

I have a super match and it is more accurate than I am with iron sights. Glen Nelson built rifles are superb.
