Re: Using PB projectiles designed for PP, as GC non PP

You can also try the moly coating the bullets. Lyman sells a decent one that used to be called MS Moly - same spray can, different label.
Some guys coat jacketed bullets in a tumbler with the moly powder.
Spray or tumbling, either works and might work perfectly on the smooth sided bullets.
Now - what diameter are the bullets. Most PP moulds cast undersize to allow for the paper patching.

With paper, you only need a small amount of lube rubbed onto the paper - even graphite powder will work with smokeless powders - your aluminum gas check should keep the base from distortion or melting. The paper patched bullets can also be sprayed with the aerosol moly.

Need more information about your bullets, diameters, methods of patching, diameter after patching, etc.




Daryl,
The mould drops them at 350 gr with the pin extended in the OUT position, and when pushed IN, depth minimum, its 250 gr
Alloy is 4:1- Pure Lead: Chilled shot for a stated BHN of about 10
I'll upload a few pics later when I can, the dia is miking as 0.4225
havent PP them yet...Just got the mold back in its Mk3 avatar, after more tweaking.I think I'll stop here.
My first attempt to 'design' a mold, if you excuse the blasphemy...
