Snuffer- Yes, Lyman has a "Black Powder Handbook & Loading Manual" all new 2nd edition, 2001. It shows loads of 40 or 60 to 120 grains of Goex 3F and 2F, Elephant 3F and 2F, Pyrodex RS and P and Select powders with round balls and conicals of all kinds in different barrel twists and lengths. Shows muzzle velocity and energy, 100 yard velocity and energy, and pressure for muzzle loader calibers. But no .40 caliber loads and no exterior ballistics. I have the same first edition 10th printing that you have, and a very good book it is.

Robby, page 270 of the 2nd edition shows loads for a .58 caliber, .570 round balls, in a 32" barrel with 1-48 twist. 130 grains of Goex 2F gave 1699 fps MV. Ballistic Coefficient (BC) of the .570 ball is .080 (a measure of streamlining or air resistance). First edition shows exterior ballistics for a .562 RB (BC .079, an insignificant difference). At 1700 fps, bullet path for a 50 yard zero is, 75 yards -1.3", 100 yards -4.3", 125 yards -9.3", 150 yards -16.6", 17 yards -26.7", and 200 yards -39.97".

If we adjust this trajectory (bullet path) for your zero, we go: 50 yards +2.5", 100 yards +5" (-4.3 + 5" = 1.3" high), 200 yards +10" (-40 + 10" sight raise) = 30" drop.

We don't know your velocity. Working backwards from the tables to get 18" more drop to equal yours, would bring us to 1300 fps MV. Bullet path from 50 yard zero = 58.88 drop at 200 yards. Raised 10" for your higher 50 yard sighting would be about 48" drop that you show. I do not know if that is your velocity.

Dan, that is a beautiful Hawken! I like that sight. I may make one like it for my personal testing use. I'm getting the parts tomorrow to build another .58 fullstock flint hawken. Tracks parts, Manton & Ashmore lock, which I like. What kind of lock is yours?
