I am looking to buy a molding kit for 5.5mm slugs to start casting my own rounds for my Huben K1. As far as I know the MP moulds design(assisted by Gregor on youtube) is extremely successful with the huben K1: 5,52 mm air rifle pellet - 8 cav. mold
That site has said that its "out of stock" for a while now...
Does anyone use any locally made molds or swagging kits for 5.5mm slugs with a huben K1 or any other high power PCP with any success? - If so I would love to hear about it please.
