I'm thinking of trying a spray can of moly to coat bullets.?
I wonder if the moly dried on the lead. Any thoughts..?

Moly was a fad that ran its course some time ago, but there may be a few that saw some advantage and continue to use it. It might be worth a try on cast bullets, but have some of the same bullets that are conventionally lubed, if possible, to do a comparison of accuracy, leading, etc. and shoot enough benchrested groups at 25 yards to satisfy your curiosity. Others would also be interested in the results. Good luck-
 
I been lubing guns with moly since the 70's on the metal parts. I've used it in the assembly of car engines. I tried leadcast moly coated bullets before it cuts down on the leading in the barrel. I'm thinking of trying to coat leadcast bullets on my own with spray moldy.

Once moly is burnished into the bores you just dry mop it. If we wash it we remove the moly.
 
Moly is a sheep or tiger in your barrel and it can stay or leave your barrel, depending on what chemicals you put on your patch.

Some like it and most don't and as mentioned, have moved on to other type coatings.

There are good and bad notes on moly but I never saw one where it "Hurt" a barrel, just hat some shooters gave it a bad rap.

Good luck.
 
I'll relate my one experience with moly coated bullets. About 1998 or so, I bought a 22-250, and decided to try working up a load for it with the then popular moly coated bullets. Sierra 55 grain moly coated to be specific.

I had a good selection of once fired brass from a half dozen makes of factory loads I had acquired identifying an accurate factory load for this rifle, used them, and found a more accurate load using Nosler bullets.

That left me with 4 boxes of moly bullet loaded once fired brass that I ended up putting in a storage bin, and forgot about.

Couple years ago, I found them, and decided to try them in another 22-250 I had acquired. But, there was a problem. When I pushed on the exposed bullet with my thumb, the case necks would crack. Push hard enough, with just your thumb, and you could snap the bullet right out of the case. All the ammo did the same thing, regardless of case brand.

I have never seen this with happen with non coated bullets in any caliber, and can only assume the moly coating some how caused the brass to become brittle over the years. I trashed that ammo, and have avoided moly bullets since.

Exactly, moly was a big thing, now it is not and it is not for a reason.
 
You'd be better off powder coating lead bullets.

Super simple, cheap enough & it flat out works.
 
I used Lyman Super Moly in the late 90's. It was a somewhat effective lube but extremely messy and difficult to keep on bullets unless you loaded them right after sizing. I had no problems with leading nor have I ever that was attributed to lube. Leading is mostly due to sizing IME. There are several lubes that allow me to shoot lead with less mess, more speed and no pressure signs that are also cheaper than moly.
 
I've used my own moly-lithium-beeswax lube in my .44 mag Super Blackhawk for the last 5 years. I use it on my 500 Smith 400 grain semi-wadcutter bullets too. It pretty much eliminates leading. I've seen no "rusting, pitting, etc." from it. So, if it's hydroscopic, it hasn't done any damage to either one of those revolvers. The stuff is SLICK and I like it. Sometimes you need to try something yourself, instead of depending on the internet. P.S: I sometime leave my revolvers in the safe for over a month, without cleaning. So, like I said, if it really attracts moisture, I think I would have seen some problems. I have not.

Don't go there ... Moly has been tried extensively and faded away because it just doesn't work that well .

Try powder coating lead bullets ... Hi-Tek Super Coat powder coatings seems to have merit !

People don't understand how to use moly. After shooting castlead moly bullets or jacketed moly coated bullets don't wash �� your barrels at all. The light gray color inside the bore is moly actually in the pores of the metal. Either run a dry patch or dry mop inside the bore and it's cleaned.
I had good results using moly I just want to coat my own bullets with a moly spray I will experiment soon with a few cast bulllets on my own.
I had a friend who worked for Dow Corning were they manufactured and tested moly.

Again once it's in the pores of the metal don't wash it out.

Moly
Eliminates all wear
Reduces friction
Prevents galling
Fights corrosion
Doesn't attract dirt.

Ok i lubed my new rifle with moly, burnished it in by hand. After I wiped my ak/akm rifle after an outing shooting it. I missed placed my can of moly. I put the gun in the safe. Months later the four of us went shooting. After shooting it I remembered I forgot to lube the gun with moly again. Opening up the cover I expected the worst. Nothing happened the orginal bluing was still on the rails. Fact this proves moly in in the pores of both metal to metal contact parts wearing against itself. Moly my guns never leave home without it. It's how we understand how moly works.
 
Molybdenum grease is used extensively on aircraft landing gears. Also used as an engine assembly lube, particularly the head. I might try some inside the 629 to see what happens
 
I have nothing against moly, just didn't want to deal with the up and downs that moly brings to the table. Things like re-working all my loads due to the increases in velocity, decreases in pressures. Then the always using moly coated bullets after that or the non coated bullets have sporadic results.

I've used moly on trigger parts and re-working bolts for decades. Never an issue with rust but the reduced trigger pulls and consistent ignition keeps me using moly for these types of applications to this day.
 
Moly treating your bore does work somewhat for rimfire. Cuts down on leading.
 
The Ohio National Guard rifle team used Moly coated bullets in their match M-14's. Half the team used them in alternating place members (2,4,6,8,& etc.) After a season of use, not one person using the moly plated bullets changed to a better scoring position! and the M-14's that moly bullets were fired in had nasty rust inside the gas system! The rust wasn't so bad that they would give up on the bullets, but for no practical advantage, why put extra wear on the system.

I have a thousand pack of Sierra Blitzing 55 grain 6mm bullets, I have loaded them in a Sako Varminter in 6PPC, They shoot fantastic but then so do uncoated! I got these for 1/2 price, or I would not have bought them. Some claim increased velocity, my point of impact didn't change, so the velocity didn't change!

Bear Creek Bullets of California made Moly coated lead bullets. I used them in several different cartridges. Very, Very Accurate out of my 45-90, and 45-70. Unbelievably accurate in my 38-55 Low Wall: Tang and Globe sights, 100 yard, 20 shot group, smaller than a Nickle, bigger than a dime! Worked fine in 45 Colt and 32-20 lever guns too. I see it as a lead bullet coating that works, but not something magical!
