Barrel Leading Reduced with Moly Dry Lube?

I bought a borescope on Amazon.ca for about $66.

Has been very educational. Is hoot 98% lead bullets in my handguns and found more leading in the throat section of the barrels than I thought I had.

So far I have scrubbed all the 38s and 357s and some of the 9mms. The borecope makes it easy to see how each barrel is cleaning up.

When I joined the CIL ammo division R & D lab, my boss told me that there are no new ideas. he has been mostly right.

I just took 500 leab bullets and sprayed them with Moly Dy Lube. I swirled the bullets around in a dish and each now had a nice gray coating. I am hoping this might reduce the leading in the first 2" of the barrel.

I will take some identical pairs of revolvers and shoot them with bare and coated bullets to see if the moly makes any difference.

I assume this has been done before.

How did it go?

I haven't tried it, but I'm curious as to the end result....
Supposedly moly coating jacketed rifle bullets cuts down on copper fouling, so it's conceivable.
 
I have made and used a lot of moly coated jacketed rifle bullets. It is a tedious process involving tumbling the bullets for hours with the moly.

Too much work for all the pistol bullets I shoot. But the spray and swish of the spray on moly is fast and easy. The borescope will tell me the truth.
 
I shot moly coated bullets out of my target rifles for years, it reduced cooper fouling which also reduced time spent cleaning. I did at one time go over 800 rounds before cleaning. I no longer shoot moly coated bullets just because I can't be bothered to moly coat them. I only clean now when the groups open up. However I am going to rebarrel one rifle this year and build another rifle, so I may change my cleaning routine. Due to a broken shoulder at the end of Feb, testing any new cleaning routine will have to wait until next year.
 
Ganderite, have you tried moly with jacketed bullets? If so did you only use the old DRY way of tumbling for hours on hours? OR did you try the EASIER WET method? The wet method is faster and I think coats better. Just wondering.
 
Ganderite…. have you tried powder coated bullets? I have been casting and lubesizing bullets for 45 years. I have tried all the lubes and alloy types available over the years, and have never been happy with the bore leading that occurred. Powder coat solved all my problems, and also reduced the lead level in my blood which was becoming excessive. I have also done side by side accuracy testing, and find no difference in accuracy.
 
Throat leading can be an indication of oversized bullet. But it also depend on how many you shoot before you had any lead. If it’s a few hundred - it’s normal to have a small amount but if it’s leading after 25.. there is a sizing problem.

I was given a few powder coated bullets to try. They worked well.

But they are too labor intensive to make. I shoot about 1,000 pistol rounds a week in a variety of calibers and while I enjoy loading, I no longer make my bullets and have limited desire to prepare them.

This dry moly only takes a couple of minutes. I will do it if it helps.
