Wing Master, welcome to the forum. It is good to have you here.


As for your concern... I can prove on the range that + or - 15 grains is a serious difference. I would have to disagree with that person. Also why would they make a 30 grain pellet and a 50 grain if there is really no difference in 15 grains of powder? Roundball shooters for years have learned that a rifle that shoots excellent with 85 grains does not shoot well with 100 grains of the same powder.

My White Ultra Mag shoots great with 70 grains but not quite as well with 85 grains. Perhaps he meant 1.5 grains of powder, but I have weighed charges and have found as much as 5 grains difference. Will that make a difference? Every day shooting probably not. BUT if I were shooting for the best accuracy possible, I weigh my charges.

Also a good point.. to tap or not to tap. Everyone does it different. I slightly over fill my measure and then cut the charge with the funnel. I get a more consistent measure that way of the powder.
