    Has anyone had inconsistent long range results when running at a stability factor just below 1.4? I'm having some issues while running berger 82's out of a 1:8 twist barrel @ 2650 fps, some days I shoot excellent, some days I get LOTS of flyers. My SF this past weekend was 1.38, and I had lots of flyers. I had ~1.45 SF a couple of months ago, which was the highest I've ever had, and it shot better than I've ever seen it shoot. 100% on call shots, except for the couple of shots where the wind got me.

    Just trying to figure out why some days it hammers and other days the bullets get lost and go where they want.
