If I am sighting my muzzloader in at 50 yards, how high would the shot need to be to be on at 100 yards? I am completely new to muzzleloaders.

I'm shooting the TC Impact, 100 grains of Pyrodex, and a 250 Shockwave Sabot.

if it is dead on a 50 it should be about 2 inches low at 100

I used to be more then ready to tell you 2 inches high at 50 puts you in the bull at 100 yards. But I found that is not true. It depends on the rifle, the bullet, the powder, and the conditions you shoot. What I would do is sight in one inch high at 50 yards, then back off to 100 yards and see what happens.

My guess (based on looking through my targets with similar loads) is if you sight it in for one inch high at 50 yards, it should be a half inch high at 75 and dead on at 100.

thats true, humidity, elevation, temp,all kinds of factors,
where I live a 50 yard zero is 2 inches low at 100 and a 100 yard zero is 1 inch high at 50.

Very true.. that's one reason I stopped trying to figure these rifles out.

Best to shoot it at different distances, out to your max range to be sure.

Like the others have said, it can depend on a lot of factors. But with the load you described, from my experience 0.5" - 1.0" high at 50 yards should put you close to dead on at 100 yards. Only way to be sure is to test it, though.

IBingo: i scope and sight in a lot of muzzleloaders. There are too many variables to predict accurately where a gun sighted in at 50 yards will shoot at 100 yards or further. The most extreme case was a gun sighted in to hit center of a 2" bullseye at 50 yards when loaded with 100 grains of Pyrodex and a 250 grain SST bullet. The same gun with the same load shot over 4" low at 100 yards.

...Deleted by CalHunter... Shoot it at 100yds. The animal deserves that much respect.
