Bullet BC for 45 cal.

[Gunlaker]

Eric I use the JBM Ballistics software and a BC of .510 for my 535gr PP Money bullet. The numbers were very close to what I used at Byers and Ben Avery. Certainly enough to get me on paper very quickly. The hard part was staying there :-). Like Don said, throw in some interesting conditions and the numbers change pretty quickly anyway.

Interestingly, my first attempt at using JBM Ballistics software at long range was at my first 800m gong shoot. I was shooting nearly the same bullet, a 444540 PP Money out of a .45-110. The JBM software predicted I'd need 10 minutes more elevation than I actually needed. I am not 100% certain why the difference as both bullets fly at nearly the identical speed. Maybe the fact that I use Fg and a lube cookie in the .45-110 minimizes nose upset and results in a higher BC bullet after it exits the muzzle?
