Does any one know the ballistic coafisant of the range master sovereigns 10.3 grain?

If no one knows for sure, Daystate themselves should be able to help you. I believe they are made by JSB, allegedly from special dies, but they look like JSB Heavies which have a BC of around 0.03. If you use this as a starting point you shouldn't be far out and BC's vary from gun to gun anyway, so any quoted figure is only an estimate.
