Got a few groups tonight in. As I expected my POI shifted, and so did some of my grouping. Before with the JSB 18.1gr I was getting close to .32 to .35 inch at 25yds. Now they’ve opened up to 1/2 inch but at the same time my 40yd grouping tightened up to 1/2 inch. So I’m going to give the barrel a good cleaning since I’ve chewed my way through about half of the 500 count tin of JSBs and see how does. Also next time I go out I’m going to try to get chrony numbers in direct sunlight vs the LED method I was using in my basement.

Of course the accuracy differences could just be me rather than the tune I’ve done on the rifle itself.
