What if any prep must you do to your bore to use moly coated bullets? A friend just gave me several hundered 30 caliber Nosler partition golds.

What if any advantage is there? Pro's/cons?

Thanks.

Lots of info at www.benchrest.com. Take a look at this thread, then use the search function there and look for "moly coating". You'll find numerous threads and links.

Here's a start:

Thanks Forrest. I'll see what it says and keep your tumbler idea as a backup just in case, lol.

Why do you not like molly?

Hey Z1R, I use two things, a Moly Grease and actual Moly Powder.

With the barrel pristine clean, I form a tight fitting "Paper Shop Towel" patch on a jag and pre-form it to the barrel. I do this by just getting it into the barrel and letting it conture itself to that size.

Then I remove the patched jag from the Bore and using my finger tip place a small bit of the Moly Grease all around the patch. Then "dust" some extra Moly Powder onto the Grease from a small Beeman Powdered Moly bottle.

Then stroke the Bore 20-25 times, remove the patched jag from the Bore, rotate the patch a bit and give it another 20-25 strokes.

The tightness of the Paper Patch helps burnish the Moly onto the full length of the Bore. A little Moly Powder goes a long way when applied properly because of it's physical structure.

I finish with one last clean patch to remove any excess grease by just pushing it completely through the Bore. You will develop a feel for how much Grease to put on the initial patch and this last wipe-down is primarily a SAFETY check in case the Bore was short-stroked and an excess amount of grease is near the muzzle.

I repeat this sequence after every cleaning.

I use Lyman Super Moly Bore Creame for barrel preparation.

I get a new barrel with no Copper.
I clean the barrel with Alchol.
I push a dry patch through.
Then I burnish the bore with moly with a patch or brush with 25 strokes until the moly is rubbed into the metal.

Then when the bore is dirty with moly, I shoot a moly coated bullet through as a fouling shot.

After 200 shots, the bore cleans like it had only one shot.



Don't get any on your good clothes.

Then do you clean as normal and do this process over?

A few more "thoughts" on moly...

I just put them through the laundry with the rest of my clothes.


But seriously folks, once I get a bore burnished with moly, I keep shooting hundreds of rounds with moly bullets and no cleaning and no fouling at 3,000 fps.

The bench rest guys clean every ~8 shots without moly and every ~13 shots with moly. But becuase I am only after varmint level accuracy and not benchrest, I don't clean at all once I get going.

About half the shooters who try moly like and other half are sorry they tried moly. From being there when a couple of my friends tried, I can tell you that if you do it wrong, you won't like it. Don't get moly on top of a Copper fouled bore. Burnish moly in a bore that is clean and has no Copper fouling. The moly only prevents Copper fouling, it does not remove it.

Thanks for the replies guys!
