So I have been thinking about these ballistic calculators but the thing is they are a bit costly and I do not want to get it wrong, and its not exactly something I need tomorrow. Right now I settled for a 29 dollar Caldwell wind meter. But it does not calculate ballistics. I have a Ruger RPR but I like Hornady bullets and ammo so would one of the dedicated units be best or should I save the bucks and get a generic unit. And if I get a generic unit would it be best to get a Kestrel or some other brand? I have a Caldwell chronograph so I can do velocity measurement.
