chamfer cavity base and bottom sprue plate holes

If you’re having venting problem, take a fine stone and swipe the top of the mould where the halves meet. Not a big bevel, just a few strokes to show a “shine”. Both sides. This will be enough.
Want to sharped the sprue cutter. Chuck a #10 screw in a drill from the bottom of the plate. Pull down and give it a spin or so. Follow up by polishing with a flat stone, lightly lube and cast./beagle

On one of my moulds, the Ideal single cavity vent lines on the bands came short. Interestingly, the bullets filled out rather well, but not quite enough, probably doable but was wondering if it can be worked. If not I’ll buy buy another mould. This time check it out more thourghly before buyin one.
Borrowed a laser thermometer from a friend to check 400 degree mould temp. Running ~13 BHN

Vent lines can be extended into a cavity with a small, fine file or scribe and straight-edge (better, a small machinists square), a steady hand, LIGHT touch and patience. A decent vice is necessary too. The iron is soft. I've done a few and even have one where the straight-edge slipped and have to see an errant scrawl when I use the mould. It doesn't actually hurt anything other than my pride.

I have a small file set , but it's too big. I'll check out Harbor Freight today in the hobby section for fine files and a small square too.Vent lines can be extended into a cavity with a small, fine file or scribe and straight-edge (better, a small machinists square), a steady hand, LIGHT touch and patience.
