Funny you should say that.. try different powder. Because when I shot the other day, I was almost out of powder in the other can. So I opened a new can of Schuetzen when I was shooting that group. Now I am wondering... when you get to the end of a can of powder, many times the size of the grains have really gotten small. This is from sifting, them being bounced against each other, etc. So maybe it was in the old can of powder, I was shooting a much finer grain of powder then I normally do. Thanks for the insight. You might have set my mind at peace.
