I ordered some Grafs and Swiss last month, Grafs seems to be a excellent taget practice type powder, cheap and easy clean up, not too bad for fouling, I would order more if needed. The Swiss will be used for hunting, fouling is slightly harder then Goex, but velocity is slightly more then Goex.
In the flinters I used 4F goex priming powder and Grafs in the chamber, I did not notice nothing being slow, next time I will use some of the Grafs in the pan and see if theres much of a difference. For over 35 years I used Goex, I still would be using it, if it was like it used to be and everyone carried it for muzzleloader use. Times are a changing.
