Limited experience here so bare with me... Shot my muzzleloader the other day using 100 grains of Triple Seven / 250 grain Barnes Expander. Was able to work a nice group at 100 yds so decided to see what 110 grains of powder would do. Not much change at all in regards to shot placement on the target.

Question:On average how much of achange in powder isneeded to see a difference in shot placement? I guess there are allot of variables to be considered, but I was just curiousif there was a rule of thumb.

Thanks for any wisdom in advance...
