HI.
Well the short answer would be No. Molly coating will not make your bullets harder.
If you want to make your lead a bit harder without alloying it try water quenching.
Drop the hot bullets from your mold into a bucket of water.
Just make sure absolutely that no water touches your pot or gets into your casting mold, BAD things will happen and molten lead will go flying.
So as long as you keep the bucket of water away from your molten lead and play safe your bullets should come out at a harder BHN than just pure lead.
Molly coating your bullets will reduce friction in your barrel but so will any good bullet lubricant.
The only thing i don’t like about molly coating is that it can be messy. I used to use it a long time ago but i didn’t like the black mess it made And accuracy suffered at higher velocity.
If you would like, try some of my bullet lube it may work nicely for you. i can send you some samples, drop me a line and i can send some to your address.
Happy shoote’n

I experimented alot with moly coating cast bullets, and the results were not satisfactory, it did not eliminate leading and accuracy also suffered. It would not make the bullet any harder. On the slow side, with soft lead and bullets .001 or .002" over bore, it was okay, but when I hardened the bullets up and drove them faster started having problems, so I quit. It almost seemed as some acted "slicker" then others, and "gripped" the rifling differently, causing flyers, leading(small amount). At the higher speeds, regular lube(with carnauba) just seem to do much better.
Some folks requested it of me and I did them up for them and heard no complaints however, and would do them again because it was/is very easy to do, and in theory, it should work, and can leave the bullet unsized as some folks like.

I want to start casting for my 1911 45, so maybe pure lead quenched will be good for that caliber? If not maybe if I get some WW and add some to the lead, that might be better. I will get a BHN kit before I use them of course.
As long as your not driving them too hard in your .45 you could just cut it 50/50 with Wheelweights and use a good lube, remember some folks recommend using swaged lead bullets in the .45 Auto and they are softer then anything cast, as just the act of casting hardens things up a couple of BHN.
