Calculating BC
Posted: Mon Feb 07, 2011 11:41 am
I had some left over 62gn bullets (223) and out of curiosity I melted the lead out of a couple of them and was left with the jackets weighting 18gns.
With curiosity nagging I decided to try and work out the BC of the jackets. After some searching I found this site:

After putting in the measurements it came out with a BC 0.058!
I filled one with epoxy just what difference that makes and as it was slightly heavier it had a BC 0.061.
No idea, it they would be useful for anything, but it was an interesting exercise.
