Re: trajectory chart

Lyman Black Powder Handbook first edition had dozens. of them. It was based on speed, wind drift and distance. You first have to determine your speed. muzzle velocities can vary immensely depending on type of ignition, rifling, patch ball combination, conical bullet fit, powder humidity, and brand.

In addition, sub sonic speed bullets tend to carry their energy a bit further down range. the more a ball travels over the speed of sound the faster it decelerates as it travels down range. It goes faster the entire distance, but slows faster. The result, according to Lyman's tables is that a shooter can double the powder and still only extend their range by a small percentage. (less than 15% generally)
