I just got my first NOE mold 358-155-TC which casts great bullets but I'm having hard time breaking the sprue plate after casting. I dont have a lot of molds but none of my other molds such as Lee, Lyman, Saeco take a 2x4 to open it up. When I cast with my other molds I use old drumstick (think drums no chicken lol) and thats all I need to open and release my bullets. I had to step it up closer to a 1x3 to get this one to open after few solid wacks. Its not the the sprue plate is binding anywhere because on its own it moves freely just fine. Maybe there is a trick I'm missing with these NOE molds.
