New lee mould disappointment.

That is two of us and I let cast stuff sit around a long time. Once I start casting I normally dont stop until its dark. Lots of bullets in coffee cans for long periods of time. Years if not decades.

Same here..once I get a pot hot and a mold running good..i try to cast as much as I can before stopping.

Many times it's not the Mould but the alloy, the alloy temp and method of pouring that cause smaller diameter across one section, especially on larger bullets.

Agreed.. Alloy makes a big difference on size. Harder or smaller

Stop measuring them ... Just use a die marked with the dia. you want , size , lube , load and shoot ... Don't measure nothing ...
Ignorance can be a very blissful thing !

I tried it with a different bullet and I get severe leading if I have an undersized portion.

I normally cast 2 hours then I start getting fatigued.

I tried this mould finally after beagle tape. Well my tape didn’t last very long but I got one good cast before it disintegrated and it was still undersized. I guess I’ll try to chase down some better tape in hopes that was the issue. But really I’m bout fed up with.

Try reading the second sticky from the top. It has some good info on opening up a mold.
