adrins,

It was made prior to Lyman buying Ideal from Marlin in the 1920's. Cherry #284 was made in 1906, so #295 was from then or the next year.

HTH, Ric

You asked the question I would like to know the answer to! The vent lines are put on when the blocks are first finish milled, maybe even on long bar stock. To the best of my knowledge, all “Lyman” mould blocks are vented and so are late “Ideal” moulds. My guess is that somewhere between 1940 and 1955.

The early moulds appear to have been factory de-burred or burnished. They are easy to cast with if they are not rusty or have loose hinge joints.

Enjoy your mould!

Interesting topic, guys.  I have 2 unvented Ideal molds, a 308241, (.30 pb rn 150gr.) with a number 108 on both blocks and a 457124 with 647 stamped on them.  I have no idea as to their age, but both cast better than some newer Lymans.

Well, I thought I had learned something (one piece molds) but when the discussion turned to the absence of vent lines I realized I was missing something -- or everything.

Where would you put vent lines on a “a solid one piece mold."

If this was April 1, I would assume that a one piece mold is something you work with a left handed monkey wrench. But it is still a little early for April fools jokes.

Please explain.

How have I managed to not hear of this wonderful device in fifty years of casting bullets?

"one piece” as in not removeable blocks, i.e. the 1800's Ideal moulds where the handle 1/2 is part of the mould block.

Ah yes, I know about those. Thanks. My brain was overheating trying to visualize a one piece mold ( for tapered bullets I assume)-- with or without venting.

John I'm with you this one, John. Perhaps one of you kind gentlemen could post a picture of said mold.

i first envisioned a tapered paper patch mold too then remembered the blocks and handles being one pieced.
