Calculating BC

#1 Post by Sandgroper »

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:

http://www.uslink.com/~tom1/calcbc/calcbc.htm#jackets

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. :D

Handy link, apparently I have a small and rather heavy box waiting for me at home which I assume is boolits from Dodgyrog

I will have a measure up tonight and see what the calculated BC comes out as.
