Ideal .38 Caliber Core Mold

[Good Cheer]

The Ideal .44 caliber core molds throws a .39 caliber slug that works well with an alternative plug* to create castings for forty caliber paper patching. What about the .38 caliber core molds? Anyone using them to make paper patched boolits?

*Like for a flat round point.

I do but it's not a core mould it's a core swage die for HP swaged bullets. But I will say that it makes a very good 100 yard wad cutter that cuts a very clean hole through paper LOL.

As manufactured the .38 core mold throws a .312" diameter cylinder adjustable to go from zero to over an inch long.
I suppose cutting 8mm drive bands in it would be a possibility.

You can adjust the diameter putting a knurl on the shank. You can increase the diameter .015" more or less depending how aggressive you get with the knurling tool.
A course aluminum file will work if you don't have a knurl roller.

Hey Lead pot.
When you knurl for bore riding can you make a lubed section that engraves on the rifling?

[Lead pot]

If you look at that photo above the top PP. You can knurl it up from bore diameter to groove diameter like the bottom shell.
It holds as much as a 4 groove bullet and you can increase a bore diameter for a proper fit for the PP.

Sounds like it could be a good way to make the bore rider portion of a lubed boolit engrave on the rifling at loading.

[Lead pot]

Yes that will put lube on the bore riding portion.
