I have an 8 cavity,115gr, 9mm MP aluminum mold. I have about 8000 bullets or 1000 cycles on it and it is sticking in cavity 3 a lot and cavity 5 sometimes. I did the match thing and it works for about 20 cycles then sticks again. I cast about 1500 bullets each sitting. I’m using WW at 720 degrees.
Is my mold wearing out? Do I need a new one?
Am I casting too many in a sitting?
Thanks
Scott
