Ballistic Coefficients

[CINDERS]

What I did was sourced a WWII MKVII ball round ballistic table then used my other books to find a velocity of the modern 174gn SMK where the trajectory of mid flight for a 300yd zero which was close to the actual WWII vintage projectile. (No hope of matching it at all)
It worked out that (From memory) it was very close but as stated the velocity that the modern round had to be driven was below minimum loads for the powder I was normally using (AR2209 or H4350 for you in the U.S.)
I then had to find (Which I had) another powder where it was at the required velocity but that also was close to the minimum for that powder.
In the end of all of this data I think at the velocity required the SMK shot something like 6" lower mid flight trajectory for the same 300yd zero as the MKVII so it would be close but we are driving the modern projiectile well below the 2440fps that the normal MKVII goes.

Anyway thats what I came up with good luck its easier just to get a load that groups in your rifle go out shoot at your max distance* wanted for hunting get the sight setting note it down and go from there its what I did and countless others have as well.

Just need to find a place that I can test beyond 100 yards. My own range is only capable of that.

Although chronographing my loads and running my ballistics program has really worked out well for me with the scoped guns.
