Well I've been trying to stretch my wings with my 6.8SPC. I don't have a chrono, but fortunately for me I just recently downloaded a ballistics calculator for my motorola Q so it help a lot. I input all my data with the numbers I found posted about the 6.8SPC and bullets I was using
I basically plugged different speeds with the weather readings from the day into the JBM calculator until it matched what I was seeing on the target. Based on what I was seeing on the target I'm throwing 90grain TNT's at roughly 2950 fps.
Is this right?
