Moly Coated Bullets ?

MFI

Can you guys please tell me the advantages or disadvantages to using this type of ammo ?

The primary purpose of this coating, as I understand it, is to eliminate leading problems in the barrel and therefore to facilitate easier and less frequent cleaning; however, it leaves its own messy residue in the bore which, if left in there too long, is a bear to clean up. A dealer here recently was asked to clean up a customer's pistol after the guy had been using Moly bullets for quite awhile without cleaning the bore. He had an awful time getting the stuff out.

I use moly bullets in my .223rem, slightly less velocity, higher accuracy, less cleaning, less wear on the barrel. Thats about what it does and what its designed to do.You'll hear alot of rumors about how it could cause microscopic pitting, this is a crock, it will actually help in preventing pitting.You may also hear rumors about how it will make your barrel dirty with gunk and less accurate. This isn't true, yes it leaves residue in your barrel. Its the same with copper bullets, leaves about the same amount to. The only difference is it comes out easier than copper, so you get abunch of dirty swabs. When you have copper residue its alot harder to get out, and after you clean all the powder residue out of your gun, you may think its clean, but its really not.Thats another thing I almost forgot, powder residue seems to stick less when you use molly bullets.Before you use molly coated bullets you should thurougly clean all the copper out of your bore, use a specific copper remover for guns, and brush stringently, you'll be supprised how much is remove.And if you ever decide to go back to non-moly bullets, then you need to thuroughly clean out all moly in your bore first, otherwise you'll find your guns shooting very poorly...If you have any questions about moly coated bullets or someone tells you something your not sure is true, then feel free to email me, I shoot moly and have done alot of reading on it. gunsmithlee@hotmail.com

Once again, I disagree. It will leave it's own residue in the barrel which is exactly why I stopped using it. It does group great,...at first,....then it leaves little balls of moly in the rifling. At this point my groups start to open up. I have used it and have seen my own results. I can't say that my experience is the be-all, end-all test, but I can attest to what it did in my rifle. Incidently, all of my benchrest buddys have stopped using it as well.

I will also never use moly in my rifles againeither. I never had a problem cleaning copperout of a barrel but when I used moly, I nevercould get it completely out. I accidently left a rifle sit in my safe for a while aftershooting moly and the barrel pitted. But thisis only my experiance.Brian

justc- The balls in your barrel were probably not molly but powder residue.Remeber, using moly should not change you barrel cleaning routen, it will still get dirty, but will have less copper build-up.Bikerbrian- Removing moly from your barrel is like removing copper, you will need a special cleaner, one thats designed for removing moly. Moly will not cause your barrel to rust, there is about a million different reasons while your bore got rust in it, but I can assure you its not from the moly. I have been firing moly thru some of my guns for over a year now, and have yet to have a single bore rust or corode. The reason yours rusted, I would guess is because lack of care, you proabably didn't clean and lube it properly.Moly isn't for everyone, I wouldn't recommend it for anything other than plinking or benchrest use, and honestly only for experienced shooters who will know how to use it to their advantage.

I might have beleived the powder residue idea if the ammo wasn't premium grade ammo. I have never had any load, not even cheap ones, leave any noticable residue in my 26" barrel 7mm mag. I clean it at the very most every 15 rounds. That is not enough firing in my opinion to leave any noticable residue. Also, I have never seen the balls since I have not used the moly bullets. I could only get 5 or 6 bullets to group well ( I define well more stringently than most) before they started slinging off the original grouping. I have only ever seen this with moly bullets. I can't say it will happen to all, but it sure happens in my gun. My Sendero will group "box stock" federal premiums 150 NBT into 1/2" and often less an 100yds with no headspacing work, no pillar bedding, just a trigger adjustment. I know it is not the gun, as it will do this with core-lokt bullets as well. The moly bullets came close, but like I said, only for 5-6 rounds. I can't accept that performance as I often shoot 10-15 times on any crop damage hunt at ranges of 325yds and up. I have said that I can't say this will happen to everyone else, but my 222 and 7mm will not group consistently with moly rounds. Just my .02

i myself was thinking of using moly bullets, but after talking to dealers in my area and one has removed moly bullets off the shelf,because the residue it leaves behind needs a special solvent to remove it. besides, if you clean your gun properly you wont have problems of lead or copper buildup.the practice of cleaning the gun after each use is the way to go. regardless of what you use, you still have to clean the gun!, so why possibly make things worse. keep it simple...good luck!

I honestly think the worst thing cartridge manufacturers did was make factory moly ammo available to the public. Like I mentioned before, I only recommend it to the experienced shooter who knows how to use it to his advantage.JustC-I don't know what to tell you, I wasn't there to be sure of exact cause.Like I sort of mentioned before, I use moly for certain of my own personal applications and do better with it than I would without it, but it was only after I learned to use it, and learned what it was for.

yankswin-just thought I'd say, that the only off the shelf moly-coated factory ammo that I liked at all was Black Hills 68gr bthp ammo, everything else sucked. Unless you handload, I'd advise staying away from moly.
