Retro Wrote:OK the gun is built on an Anderson 80% lower with Anderson upper. 20" Odinworks barrel, bolt and carrier, non-adjustable gas block, rifle length gas tube, Odin foregrip, Rock River 2 stage NM trigger, H2 buffer weight with carbine length buffer spring. I just installed an Odin Atlas 6.5 compensator as well. Glass is a Primary Arms 4 -16 x 44 with Primary Arms cantilever scope mount. All of the ammunition is hand loaded and today they were all variations of Hornady 123 Amax. Powders used were H335, CFE 223 with a little bit of IMR 8208 for good measures. The brass was either new or once used Hornady and the primers were CCI 450. All of the loads came straight out of the 2nd edition Grendel book or off of Ammoguide.com. Scope mounts are tight and so are the scope clamps. The temperature was at a balmy 38* with a light breeze from behind. I was shooting on a 100yd range. I was shooting benchrest with with Caldwell bags for support front and rear. On one group I managed to put five rounds into a 1" square. Most of the groups had at least two rounds touching. I only started shooting about a year ago so my skills still aren't the best. I appreciate any and all help the Horde can give.

Vertical stringing from a rest when shooting a AR is about the most common situation you will find. Comes down to how you make your firing position and attentional focus while shooting.
So, create a position around how you sit at your bench. The rest and your position together must fit you like a glove and be such that when you look through your sights, you see a decent sight picture without having to shift a bunch of stuff or cock your head in some odd position. Make the rest and your rifle fit you first. It needs to be very firm. You will know when you have something because when you slip into your position and see that it is pointing your rifle for you, and that you have solid control of the rifle, your confidence will come out and you will be able to approach your string knowing that if it doesn't end up right that it wasn't you.
Once your position is developed, fire your string in a sustained fire mode, a breath or maybe two between shots as your sight picture settles into something you see as perfect, then your shot. Recover, repeat. I do not advise you look at your group until you have fired your string. Call each shot, too. Then look. Most likely if your position held up for your string, and you focused on sight picture for your shots, you will see performance that is more likely a result of your gear and ammo than you.
Something a bit more advanced which should improve your ability to ID a perfect sight picture is for you to have a sketch of your target next to you and once you fired your string, mark on that target where you believe your shots went. Then compare to your actual shooting.
