I have been running my MiHec 9mm124hp 4 cav and have an issue that I wonder anyone else is experiencing.
My sprue plate has a slight gap on the end opposite the hinge screw resulting in the occasional "flange" around the base of the 4th boolit.
This will show up when the mold is running nice and hot and fill out is looking really sweet. Just a little too sweet on the end with the gap.
I have the hinge screw as tight as I am comfortable torquing it in brass.
Seems like an easy cure would be a flanged screw on the opposite side of the sprue spate to hold down the plate to elliminate the gap (like some of the "other guys molds").
Anybody else deal with this?
