I just scored an unfired MK85 blued with laminate stock. Picked up a 209 conversion kit and an extra 100 red holders, they are getting scarce. Research says BH209 is too hot for plunger type guns, but 80 grains of it is the same velocity as two 777 pellets. Not sure if I'll try 80 gr of BH209 or stick with my old 90 gr Pyrodex Select that work so well in other Knights. I use green sabots and Hornady 240 gr XTP.
