Was wondering if there is database for say 177 and 22 calibers of ballistic coefficients. If so, please point me in the right direction. If not, would this be a worthwhile undertaking for this forum. At least to select these 2 calibers to start out. I am talking about pellets like Crossman Premiers, H&N, JSB and RWS that most serious shooters use. Just a thought. Thanks in advance for all replies.
