As some of you know I'm fairly new to casting balls and I have been casting .380 and .454 with Lee double cavity molds. The molds do a good Job if I let the mold heat up first but it seems to me that the sprue cutters are not doing a real good job. They seem a little rough to me. The cut is clean but it appears that the cutter is dragging a little. Any ideas to make it cut a little smoother? Mike
