I just purchase a Pedersoli mold for Remington pattern .36 on Ebay, the mold is new. However it is very difficult to open and the sprue cutter is very stiff as well. I have not used it or even put lube on it as I am waiting to hear from the seller, who seems to be very ethical. Does anyone have any experience with these brass molds and is this a normal condition which requires a lot of cycling to break them in.?
