Rio Salado "Legacy" Match

So, I choked with a 204 out of 300 at Washington's Birthday.

I did much better at the 2011 Legacy match at Rio.  This was a 50 shot match, all shot at 200 yards.  I shot a 412-2x out of 500 possible.  That's a personal best at 82%, and I'm pretty happy about that.

I ran this match with my 1:9 twist AR-15, shooting factory Prvi Partizan 75gr match ammo.  No keyholing, so my 1:9 can stabilize 75gr ammo.

Things learned:
1.  I shoot seated MUCH better with an AR than an M14.  The extra height to the sights, and the extra vertical distance on the grip due to the pistol grip, help me with my long body from the seated position.  My seated was my best component yesterday, and I got away with a 94-2x on it.
2.  I think I've picked up on something with standing.  I'm eager to try again.  I did a 72 on my standing this weekend, which is certainly not spectacular.  I had 1 miss.  But, towards the end, I realized I could control a component of my natural point of aim with my support arm, based upon my wrist's angle at the delta-ring (I support the AR's barrel with a reversed hand grip at the delta-ring for standing).  Rotating my wrist helps "settle" the rifle in the direction I want to go.
3.  Buttstock tension into the shoulder pocket is really important from prone.  When I shot slowfire prone, I noticed that my 7-ring hits were all happening when I'd slack off on pulling the buttstock into the pocket.  When I'd tighten back up and pull with the pistol-grip straight back into my shoulder firmly, my shots would tighten back up into the 10 and 9 rings.  Tight-tension into the pocket = hits in the 10-ring.  Light-tension into the pocket = hits in the 7-ring, down 2MOA.
