When trying to fine tune my BC for the JSB 45.75 gr Diabolo pellets in Strelok Pro, when I hit calculate it gives me an error window that states "This is not allowed. With nonstandard drag function ballistic coefficient can not be calculated." I use the GA Drag-function. I assume the airgun drag function for the Diabolo pellet is considered nonstandard, and you cannot use the truing function with it? Does anyone have a workaround? Does anyone use a different drag-function for pellets with any success?
