I use 15 in my brasser, (under the recommendation of Hawg) and it works wonderful! I put a felt wad between the powder and the ball, but don't use the filler crap. I have not noticed it to affect accuracy in the least bit, and I really don't feel like blowing corn meal all over the place. I'm the only cap and ball guy at the range I go to anyways, and I think it would confuse them as to whether I was shooting or making dinner
