to make my charts match my trajectory I run the BC of the 140 berger to .7, this makes POI match POA to almost 1200 yards.
Thats in a 6.5 Gibbs running the 140 at 3160 fps using 62.7 gr of retumbo.

If your going through hell, keep on going, don't look back, If your scared don't show it.
You might get out b'fore the devil even knows your there.
