w44wcf" I agree with you the Pyrodex is very corrosive,when useing this type of powder I clean the bore after every ten shot's or so. I keep a drinking water bottle on the bench with water and Dawn dishwashing detergent in it . And the fired cases go into this after fireing. I use the same soapy water and plenty of rag's on the bore before leaving the range and the rifles, and cases get another going over ,back at home before going back into the safe. I do the same routine when shooting Swiss or Goex. The two latter do clean-up quicker. I find Pyrodex to be harder on brass than reg. BP. And it stink,s more. But it shoot's fairly well ,and is safe in the gun ,a big + to me. It has another use, If It start's getting crowded at the range ,on the bench's next to me ,well that's when I pull out the Pyrodex Load's for testing. Then I get some elbow- room. Work's every time,,,,,,,,Dusty
