It looks like the 69gr bullets at 2850fps goes sub-sonic betwixt 700 & 800 yards on the JBM website. I have shot the 69's and the 77's both at 600yds and there is a very noticible difference in how they act in the wind though I've shot some good scores at 600yds with the 69's.The classical equation to calculate gyroscopic stability is as follows. ( Sg S g) is the gyroscopic stability factor, and must be above 1.0 if the bullet is to remain stable. Sg = 8π ρairt2d5CMα A2 B S g = 8 π ρ a i r t 2 d 5 C M α A 2 B. The variables are as follows: The gyroscopic stability factor. A bullet is stable if Sg S g is over 1.0.

Joined Dec 8, 2009 Messages 5,668 LocationSo, for these six loads, we fired five-round groups from a benchrest at 50, 100, 150, and 200 yards. We zeroed our rifle at 50 yards, so that’s our starting point. At 100 yards, the subsonic loads dropped more than 7 inches. The Stinger has about 50% more velocity and it only dropped two inches. Moving out to 150, the gulf between the fastest ...The JBM IDPA classifier application is a simple application for IDPA classifier practice.
