I never realy paid much attention to the pros/cons of Moly treating of bullets and firearms....I noticed that a lot of Varmit bullets are moly coated....and seen a moly process for moly coating bullets useing a tumbler in the Midway catalog.

I dont know Jack about moly....read somewere that you have to treat your barrel and the bullets and is a royal pain to get out of your gun....

So what is the pros/cons of MOLY???????? Aside from high speed rifle loads would Pistols and slow moveing (say 45/70) bullets benafit from it ???????? Does it realy help high Speed Rifle loads???? What about Cast lead bullets and Moly....would it prevent leading or just junk up the gun with moly coated lead ????? If you moly coated cast bullets would you still lube them???? Is moly good or bad.....the next wounder thing or just junk snake oil??????

Thanks All.

I have played with it a bit and found that it just makes a mess and slows down your round. yes moly is slick and remember the bullet going down the barrel has reduced friction this translates to reduced drag in the barrel thus is reeduces the fps because the pressure doesn't develop. plus its a mess in an autoloader you have to push on the bullet to load your mag and you hands will be filthy and for it to work they say to not clean your rifle until 500 rounds.

Nosler was telling me that Moly is just a gimmick to sell more expensive bullets

Moly is also hygroscopic (attracts water). I have never and will never use it.

Shuan,
If your going to moderate this forum you should make sure your answers are correct.

1. If the load is the same a molycoated bullet gives lower vel. due to reduced bore friction. The powder charges are increased when using coated bullets to bring the vel. back up to the same level.

2. Moly poses no problem in an autoloader as the powder residue is many times greater than any mloycoating that might be left in the gun. Yeah you can get some on your fingers but on a varmint hunt in WY. I went through 422 rounds(all molyed and single loaded) in one day and didn't get my hands dirty from the moly. After the moly is applied it can be overcoated with carnubia wax to keep your hands clean.

3. The cleaning interval is 80 to 200 rounds depending on the barrel smoothness. I don't know who told you 500 rnds but they lied. When you clean after shooting with moly you must lightly coat the bore with oil as moly is hygroscopic(draws moisture from the air) a light coat of oil is all that's needed to prevent this.

4. Nosler claims moly is a fad because they don't sell any molycoated bullets. I got my earliest info from Walt Burger of Burger Bullets at the Shot Show in 99. He and his wife Euncie are both in the Benchrest Hall of Fame and they shoot nothing but molyed bullets. Oh, the first experiments with moly on bullets was in 1923 so that's an 80 year old fad!

5. There are moly removers on the market now that remove moly from a barrel(I think Butch's bore shine makes one).

6. I shoot only molyed bullets in 5 varmint rifles from .22hornet to 6-284 the longer I can shoot accurarly without having to clean the happier I am. As an example in my .243 I used to have to clean every 15 shots to maintain acceptible accuracy. With the molycoated bullets I can shoot 70 to 80 rounds before it needs cleaned and it only takes 10 to 15 min to clean, the moly helps that also because there's no copper to remove.

Dave this is good info but let me clarify the Winchester Combined Technology a moly coated bullet is produced by Nosler. Believe me I know I spend several weeks a year at their HQ. They do see it as a fad.

Also the 500 round numbers I recieved were provided by Midway when they first introduced their tumble application Moly. I see where you are coming from regarding the addition of additional powder to compensate for the drop in Velocity - at the time when my business was experimenting with the use of it we could not find any information certifing loads according the SAAMI spec's.

As to the function in an autoloader my only reference is that I have applied the moly as prescibed by midway on lead bullets and jacketed pistol bullets and had the moly come off on my hands. My personal choice is not to use them in any of my rifles and I shoot a lot as well but I prefer to brush the bore after every 10 anyway for accuracy unless I am using my autoloader on Varmints.

What about in pistols?????? LEad bullets?????

haven't seen any difference in my hand guns between lubed and unlubed -- I use a hard lead that doesn't fowl the barrel so this one is up to you like most things its preference.
