I am trying to use a five cavity, 30 cal. NOE that is about 4.125" long.
I am using Lee 90005 handles.
When I try to open the mold, the rear (closest to handle pivot pin) mold pin seems to hang up. The front opens a bit allowing the point of the bullet move down and wedge the mold open, disallowing the blocks to move back parallel so that the pin can release. Rolling the mold sprue plate down minimizes the problem but takes time to perform and you still need to fuss with it.
There is nothing wrong with the mold that I can detect and it separates nicely by hand.
The problem exists with the mold oriented sprue plate pivot close or far.
I can get them to open with a lot of fussing, but not fast enough to keep the mold hot enough.
One other thing that seems to make it work, is to fill only the farthest three cavities.
Is this a problem with the Lee handles that would be remedied by NOE's handle?
Is this a function of an extra long mold that I just have to live with?
What do you know about this?
