nosimij, I see you are from NE Ohio. Try Fin Feather and Fir. The Canton store had powder (but not a lot). Also, I believe there is a gun show at Medina County Fairgrounds Sat. and Sun. You should be able to find powder there. As for over belling, if there were just a few...but since you have so many I can't think of a good way to correct the situation.
