I have a bullet mould block that is aluminum that I need about .136” taken off the top. I need a flat, fairly smooth surface left for the sprue plate to ride… Anyone out there? The local shops want 4 to 5 hours and setup fees to work on a 22 dollar mould block…

How big is the block ?
Pic ?
I want the bottom driving band and lube groove milled off.

Another view when done, exposes handle pin holes:
why not just hand lap it on a lapping plate ?
( a piece of 1/4” thick glass with wet sandpaper should work well)
May end up going that route… the top cannot be polished smooth, the machine marks provide venting when pouring into the mould. I also cannot remove the handles until the pins are exposed on the top and bottom. Quite a bit to remove and maintain true without some kind of guide, or at least I think it would be.
So you just want to make shorter bullets ?
Should be dead easy on a mill.
Will study it more tomorrow.
Bed time on my planet.
If nobody else steps up, send me a private message here.
That is exactly what I want to do… this was designed for the 32 H&R Magnum and maybe the S&W Long but is to heavy for the 32ACP. When shortened the ogive is perfect for a semi-auto and the weight falls right about 75 grains.
Will wait a few more days to see if there are any takers in the states.
