What I see in that target is that you have a pretty good load going for a 300 yard range and a 10" bull.
Throw away hole 5&10 your under a MOA by estimate.
Looking at the shot placements 1&2 3&4 7-8-6 I call that more of a sighting error that Rick is talking about especially using the post if that is what your using this can also happen with a round aperture to small.
I cant see a problem with a load having a vertical problem in the order of those shots.
I don't know if you have ever shot a service rifle, but I would try a post that matches the diameter of the target and hold that fine white line Rick is talking about, The better you vision the closer you can hold that post on a slightly blurred bull.
The post diameter matching the bull close will eliminate the horizontal barring wind conditions also the vertical in a no wind condition.

"being a right handed shooter is a slight pull to the right normal?"
I would say you would push it right more by tightning the grip at the break then a pull left.

Front sight?? Post or aperture?? If post...under certain conditions of lighting and attempting to use a 6 o/clock hold....it's very difficult to tell if the front sight is exactly at the bottom of the bull or if it's eating up into the black a bit. To alleviate this problem to a degree...try using a 'line of white' between top of post and bottom of the bull. Research has shown that groups as small as 1/4 MOA can be attained using this system of aiming. If using a front aperture.....DO NOT get caught in the trap of using one that is too small; one that closes down the interior of the front ring tight around the bull! THAT is a common error that most rookies make when using a front aperture. The eye cannot ascertain any aiming error when this is done and your results will be much better if you use a large front aperture....one that will give at least 2/3 more area around the bull than the bull occupies itself!! The front post or the front aperture should be absolutely clear at shot break with the bull being a slight blurr/out of focus! You WILL NOT be able to learn to CALL YOUR SHOTS unless this last tip is applied!

MERRY CHRISTMAS TO ALL!

I'm done!

thanks Rick, I am using the smallest aperture that I own, but I can go up 2 sizes, I am using the crosshair aperture with circle in center

When I was shooting Service Rifle....I found that I shot better groups/scores when I used a post front sight just a bit wider than the bull! This all goes back to a 'concentric issue' involving the way the eye sees error! If the post overlaps the width of the bull a bit....it was easier for me to ascertain a good centered up hold rather than using a post that exactly fit the width of the bull.

I agree that a wider post is better then a post to narrow. I never had a problem with a post that matched the bull and If I could not match it I would change to a wider one and I still prefer the post over the round front aperture but with that dark floater I now have I dont see that fine line anymore and the black bull seems to split in two as the light changes.
