I shot 3 rounds to foul the bore, then commenced to testing 3 shot groups in 10 thou increments.

I stopped at 40 off, then shot a 5 shot group at 10 off to confirm the 1st three. First & second shot almost touched, then got caught in a push that went right. I waited for the flags to settle down, & the 4th went back in the group. Wind picked up a little, so I got anxious on the 5th, held left, and it went left....dammit.

I shot one more quick group with 40 grains, & called it a night.

When I went down to pick up the target, I was surprised how much the wind would pick up and funnel towards the target right at the pinch point, half way down the range. Kind of a vortex thing. Of course things died down while picking up my stuff.

Testing's over........
