Not to be a spoil sport but the BC of a 5.45 is nowhere near .500 meaning the chart is wrong....

Dave's only a spoil sport if he says it's wrong but does not give his correct data............

So what is the correct BC for 5.45x39 bullets?

I wonder how my 24" RPK barrel would change those numbers?

Probably boost the velocity by a 100-200 fps.

David Fortier chrono'ed Wolf 60 FMJBT from an RPK74 at 3033 fps. Found it in an older Shotgun News. I used that number in an online calculator to get some numbers. I'll post them if anybody wants to see them.

I ran the numbers through a few different calculators mostly using the .500 BC. One calculator had a BC calculator in which I plugged in .214 for the diameter of the bullet, 60grs for its weight, at that it was FMJBT. The BC calculator came back with a BC of .366.
