Hey guys I was really late getting a new muzzleloader this year.

I haven't had a chance to sight it in so my Dad offered to do it for me. The problem is that the longest place he had available was around 25yards.
He has it shooting about 1/4" high at 25yds and I am curious as to how much it will rise or drop at 100yds.
The gun is a 50cal Traditions Buckstalker using 250grain T/C Shockwave bullets and 100 grains of Triple 7 pellets.
I wish I had more time to take it someone at 100yds, but I just won't have the time/daylight to do this before opening morning (this Saturday).
