I ordered a 5 cavity 358477 mold from Arsenal. I cast using a Lee 4 20 pot. The front of the sprue plate bumped against the front of the pot and I couldn't fill the last cavity. I started going in at an angle but didn't like that. I turned the mold around in the handles with the tip of the sprue pointed at me and it worked. I think I like it better this way. I am sure someone has thought and done this before. This is is no way a ditch of Arsenal molds. this is the finest mold I have ever cast with.
