Slight problem with a bullet mold

[bernie]

I have a bullet mold that I am having a slight problem with. It is a brass NOE 4 cavity dropping a 148 gr HBWC for .38 special. My problem is that the bullets will not come off of the pin for the hollow base. I mean they stick. It takes pliers and a pretty good tuck to get them off. How to I get these to release properly? I have smoked them. I have used the molds several times and they are just as stubborn now as when they were new. I have some MP molds with pins and after I used them a couple of times they work just fine. What do I need to do?

Polish the pin would be my first thought. Is it concentric? Might have a slight bend in it helping the bullet stick.

Try a number 2 pencil on the pins

You might need to run the mold hotter

Maximum heat to frosted bullets will cause more shrinkage, as bullets cool in the mold. Note that frosted bullet may be undersize in diameters.

My take would also be to polish the pins first.
Make sure to polish all of them the same amount (have a pal time you?)
if the bullets weights are close between the cavities.

A suspended graphite solution - I use the old NEI mold prep on stubborn mold blocks - properly
applied to the pins might help as well.

Hotter and cleaner. Spray out with brake cleaner and run hot. I like frosty bullets, but I know some folks don't.

Pins need to be kept hot. Polishing won't hurt either...
