change in amount of powder...
I am currently only shooting 100 grains of triple 7 pellets (2) along with a 250 grain bullet out of my muzzleloader. If I change the amount of powder up to 150 grains, how much would my shot be off, say at 100 yards? I know that I should go to the range, and I will, but I was just curious to what I should expect at the range.
