My TX200 and Diana 34 really like the 8.4gr Air Arms Field pellets with the 4.51mm head. Does anyone know the ballistic coefficient for these pellets? Chairgun Pro list a BC of 0.021, which is the same as JSB Exacts 8.4gr.The AA Fields seem to buck the wind better than the JSB Exacts in both of my air rifles, so I suspect the BC may be a little higher.Some of you may say that the AA Fields and JSB Exacts are the same pellet, but they are not from my experience. The POI and muzzle velocity are quite different, and the skirts on the AA are a little bigger in diameter than the JSB, while the head size is smaller on the AA.Thanks!
