Hey all, I have a ballistics question for ya! not only external but internal as well! First off I'll present the question... What is the difference in muzzle velocity between a 26" and 28" barrel when using a black powder substitute? The load charge is 120-125 (for operator error) grains loose powder 777 ffg, and the projectile is a barnes TMZ copper slug in a sabot. All testing I've seen in regards to velocities and their corresponding charge/bullet combo's have been out of a 26" barrel... So here's the elemental question... What kinda muzzle velocity can I expect from the aforementioned charge and bullet out of a 28" barrel?
Thanks in advance for any answers...
not that it's relevant, but this has a b.c. of .210, which seems pretty high...correct me if I'm wrong.
