I shoot lead bullets in 45 acp and 44 mag.

After a few hours at range or gun club the barrel is of course full of lead.

I want to know what is involved in moly coating lead bullets. I am currently buying lead bullets that are already sized and lubed (local guy eliminates freight). I have a tumbler.

Advice?

Thanks,
Fred

Start shooting jacketed if your going to shoot alot between cleanings. I personally don't like shooting lead in my auto's at all. Too dirty from the lube. KN

kn,

I am required to use lead at gun club...plus it is much cheaper.

I do use a bore snake every 30 rounds or so but lead still fouls everything up.

Boy I can see how that could be a problem. I would think that molly would cause similar problems in an auto loader. I have always heard that molly tends to build up in chambers. KN

Don't use moly...that will only complicate matters. :evil:

Complicate how?

Thirty rounds is a LOW number for lead to start building up. Leading is a function of many factors; bullet hardness, size of bullet, condition of the barrel, lube and pressure. Before you give up, let me suggest two things. If you are shooting low pressure loads, bump it up some, being careful to stay safe. Hard bullets are a selling point, but being too hard can cause leading if the pressure isn't high enough to obturate the base of the bullet. The other suggestion is to get some Lee Liquid Alox and coat your bullets. Worked for me. You might go over to the Cast forum and ask for some help over there. Personally, I never worried much about having a dirty pistol. Never had one to fail to shoot from fouling.

One local gunsmith has a 6.5 mm wildcat of his own design that gets around 3700 fps with a 120 gr bullet. He told me that he tried moly-coated bullets in one to cut down on jacket fouling. I forget how many rounds it took but in a very short while his barrel ( a Hart I think ) had a build up that he said was like it was baked on and he could not get it out with any amount of cleaning. He finally had to send the barrel back to Hart and have them fix it. So it seems that at very high speeds moly can really cause some problems.

moly coated bullets

I believe most of the problems experienced are due to an inferior method of moly-coating. I use the method marketed by MidwayUSA and have never had a problem. After tumbling for about 45 minutes I remove the bullets and place them in an old towel and agitate to remove any excess moly powder. The moly bore treatment is useless; don't buy it. Also avoid any spray treatment. It takes about a dozen rounds before you will see the effects as the moly also coats the bore. I run a dry patch through the bore about every 50 to 100 rounds. I give the barrel a thorough cleaning about every 200 rounds.

The moly treatment shrank my groups by 100%. I also treat my jacketed auto rounds to improve feeding. I cannot tell a great deal of difference in lead bullet's accuracy but there is less leading. I have not tried the treatment on swaged bullets.
