Looking good, Roger - nothing like a bit more powder to tighten things up. I agree with LB. For 100yards, 100gr. to 110gr. 2F - might just shoot similar to the 75gr. 3F at 50!! The 2 off to the left usually denotes a bit of breeze out there, or maybe light change in seeing the sights, etc. Nothing serious though - they are close together which is meaningful- maybe - but, I would try 2F - it just takes a bit more of it to do it's work.
