Can anyone tell me where I can find info on stability factors and calculators. Thx
JBM ballistic has some info on that. Robert McCoy's book has all the details. The Excel sheet BC calculator on Lilja's (barrel maker) site, gives the twist needed to provide a 1.5 stability factor (for a given set of bullet parameters). I think it implements McCoys code.
