Thanks _ for the input - I'll keep trying and looking for a pattern. I have a 4-12x swift with adjustable parallax error on my Omegashooting off a lead sled off a concrete wall. The crosshairs are not moving when I squeeze.

Shooting yesterday - very little wind and most of the bullet path is cover by brush or spruce trees.

150yrds.
Shooting 195 gr Duplex dead center
100gr T7FF

I have RSI shooting computer program to analyze target results.
Here are the results:
Max Spread 3.51
Vert Spread 1.67
Horz. Spread 3.38

I also shot every other shot at 90 Yards. And put every shot inside 1.5” group.

Maybe there is more wind than I think- even though I can’t feel it. Maybe I am getting to picky.
