Just seen the groups.
I have to go get the wife from work but my initial thoughts are ...
Damn good groups, all of them at 55 yards with a springer ( feeling terribly hopeless ).
The 45's which seemed to slow down the most on the downrange chrono figures seem to have been drifted right by the wind a tad more than the others ... which I suppose makes sense ( but they've held the same vertical ? ).
Thanks again Bri.
