Thank you

I've calculated the 311247 and it is roughly .436.

Thank you, anyone on the 311365 ?? out of my alloy these go about 195, as cast and comparing the FB design to a Speer 200 SP A .560 I'll make a SWAG that it's close to .500 ???????
BUT would like other opinions

B.C. of .517 (approximately, when using the calculator in the next post) :) for the 311365
