Clean your new Impact with Ballistol if you can find some. Gander Mt. and Midwayusa usually carry it. It is the best I found for cleaning BH209 residue. Works well on the barrel and breechplug too.
Blackhorn 209 is a great powder to use with Federal 209A primers. CCI 209M primers are supposed work well also though I've only used the Federal 209A's.
