If you can tell me the barrel length Cal of your gun Round ball weight what you have the gun zeroed at in yards & what powder your using. I could give you a educated guess how many ft/lbs it will have at any given yardage to your zero point. Also how fast it is moving in FPS or feet per second. Being a lead ball is going to limit killing range tho as it will drop fast & bullet weight retention is not very good in 90 to 100% lead bullets - balls.
