round ball velocities for r/b in springfield

can anybody tell me what kind of velocities to expect from an 1861 springfield, shooting a .570 round ball behind 60 gr. of either black powder or pyrodex. (dont like the idea of using pyrodex but its all i can get right now). keep yer head down! rebslayer...

I am showing this data for you:

58 caliber (.570 round ball)
.010 pillow tick patch
Crisco lube
G-O Black Powder FFg

(40 inch barrel length)
60 grains FFg..... 1274 fps.... 1012Ft/lbs.

I am also showing the same load using a Zouave, (32 & 26 inch barrel) just to have something to compare with...

(32 inch barrel length)
60 grains FFg..... 1030 fps.... 612 Ft/lbs.

(26 inch barrel length)
60 grains FFg..... 847 fps.... 414 Ft/lbs.

I hope this helps.

The "LYMAN Black powder handbook" has ballistic tables at the end, very handy? I Use them to test my home made powders against Geox powder reference. On the Net too, you can download little shareware ballistic programs like "Ballistix" or "Balltraj". I get velocities of 1600ft/s with 63g of homebrew which compare with Geox. This is an optimum load for power/accuracy ratio. (50cal, patched RB, 33" barrel)
