Moly coated bullets

[mshm99]

Does anyone have an opinion on whether moly coating bullets is worth the effort. I have never heard anyone say anything good or bad about them.

I haven't been useing the molly long but have found it keeps the barrel cleaner.I am about ready to go back to not useing it because it is messy to put on.I have only been useing it in my target rifles anyhow.
If you look in my last post the 150 bergers were mollied but the 135 wasn't.Don't think it hurt the accuracy any.Will have to do more testing.
Richard has been useing it a long time so he may give you his thoughts.

I've been using them in my 22-250 for years and I personally like them. Others feel very strongly against them. IMO they shoot everybit as good as none coated and don't get the copper build up. I buy them already coated so the only mess is on my finger tips when loading them into my bullet in the bench press.

[whyohe]

i have heard that the moly coating is hard on the barrel. is this true? some have said since it is a powder its like sanding the barrel? just wonder what you thought.

[Richard]

Don't believe it, Whyohe! I have been using it since the mid nineties and in fact shot the former 1,000 yd. world record using it. I moly coat every bullet I shoot in both my rifles and pistols. And once I get to shooting sabot less, I'm going to try moly coating them. For me, it flat out works. In my custom barrels,(can't speak for some of the rough factory barrels) I get little or no copper build up as evidenced by my Hawkeye borescope. Moly is "slick" In my way of thinking, anything slick is going to cut down on friction. Less friction, less transfer of copper to the inside of your bore. I have found no degrading of accuracy. I cannot say it improves accuracy either.
Here is the best description of the composition of the moly platelets: Picture throwing a bunch of shinny magazines in in a pile.......then trying to walk on them. What happens? They slide and you fall ;D That is what moly is like. Little tiny microscopic flat pieces which "slip and slide!"
I do all my moly coating in a "Tumbler's Tumbler" using plain ole' copper BB's and a commercial grade moly from one of the industrial supply houses like Grainger, MSC or McMaster Carr.
I put the BB's, moly and bullets in a plastic butter tub (with lid) and place it inside the tumbler. I use foam rubber to keep the butter tub from getting thrown around inside the tumbler. About two hours. I use a large hole sieve to separate the BB's then agitate the bullets in a old towel to remove the loose moly. Done!

I like what I'm hearing from Richard. I did hear a lot of negative things about moly a few years ago and it got me to thinking that maybe I should quit. One thing was that it's hard to get out. Anyway I kept using it 'cause I wasn't prepared to pull 300 bullets out of the brass and reload with copper . Still have 250 left. I do like not having to worry about the copper fouling and that was a big reason I went to moly in the first place. The barrel in my 22-250 fouls pretty quick and accuracy goes then too.
One quick question. Since I've been shooting the moly bullets I can't get a reading on my chrony of those small bullets. Copper one out the rifle worked but not on the moly.

raf ,dem boolits is so durn slik theys pushed the light out o dway.

Thanks for all the info,fellas.

raf..........I run them across my PACT chrony all the time with no problem. And I mean .17's from my Mach IV at 4300fps, from my .204 Ruger, .22's (CF) you name it. I get readings on all.
Richard

[raf]

If you get your 17's at 4300 I should be able to get my 224 at 4000. I've taken my sky screens off.
Maybe if I put them back.....

[Richard]

Never use the sky screens on my PACT! At my range, I get the sun coming in from an angle and the screens would do no good since they are overhead. I have made up some side shields to keep the sun from the photo cells.

I am wondering if the moly coating adds to the diameter of the bullet in the slightest?

I would think so but doubt anyone here has an instrument capable of measuring the difference.

I have read about molly coating bullets years ago when it first came out. I read all I could find on it both pro and con. The only thing I ever read anyone saying bad about molly coating a bullet was when the bullet traveled down the bore the molly it would subsequently deposit in the rifling's and would in time become near imposable to remove.

Anyone can confirm this as truth or myth?

[Richard]

Another wives tale Art. I have Krieger barrels that I retired after some 1300 rounds and my borescope shows no sign of any type of build up. I have never experienced any type of problem I could relate to moly. For me, it just plain works!

I have used molly coated bullets for years.I have a 22-250 that gets 400-500 shots through it every summer at prairie dogs,I shoot 40 gr. ballistic tips around 4,ooo fps, after 7 years it still shoots under 1" at 100 yards. I use spray molly from Midway and after it dries I put it in the oven on 250 degrees for about 10 minutes.I have many rifles but only use it on high velocity cartridges 22-250, 300 ultra 25-06 ackley. It is some trouble but prolonged barrel life is worth it. I use an electro-chemical foul out barrel cleaner so fouling is not an issue.

First there was Molybdenum Disulfide (Moly), then there was Tungsten Disulfide (WS2) which supposedly took heat better and didn't build up as fast as Moly. The big theory with both of these is that they are sulfides, have a good amount of sulfur, and as a result creates sulfur oxide which can absorb moisture and then make sulfuric acid (acid rain) and eat your barrel. Of course if you hit it with some oil it will not absorb moisture so maintenance is the key. Supposedly the next greatest thing is Hexagonal Boron Nitride (HBN), Dave Tubbs is beating the drum on this bandwagon. Will take even higher temps and will not absorb moisture and turn into acid to corrode the barrel.

I wonder if my Oehler chrono uses a different type of skyscreen, or eyes, than other brands? It doesn't work well without the orange difusers installed. Monday afternoon, we shot until near dark, and it read every shot. The owner's manual says that the screens "see" the bullet shadow, and that very shiny bullets, like Nosler Ballistic Tips, may need darkened by a Sharpie. Seems like the dark colored Moly coating would work better than uncoated bullets?

[rossman40]

I kinda wondered on to this subject with some friends and one said a new trick he seen some of the benchrest crowd guys doing was swabing the bore with Lock-Ease. I've used it for triggers for years but never heard of swabbing the bores with it. You seen any of that Richard?

[nemohunter]

does the fact that moly is hygroscopic bother anyone??? i know it did me since our humidity here in MO is killer most of the time.

[thelefthand]

I live in central IN, and we have a fair amount of humidity here as well. I molly coat all my bullets. There are a few of my rifles that don't show much difference, but I do it with all of them to be consistant. They made a HUGE difference in my 7-08 encore which had a terrible problem with copper fowling. I also like them in my AR-15 service rifle because I can shoot so much more between cleanings. IMHO it requires LESS maintenance than the normal copper jackets.

According to my gunsmith, David Sams, sams custom guns, moly is not good for a barrel. He said it is #$% to get out and that it was molycarbicacid or something like that, and can harm a barrel if it is not all removed perodicly.

[Richard]

There are a lot of opinions on a lot of things. If you think the person giving the opinion knows what he/she is talking about? Then go with what they say I can show you many knowledgeable people who shoot moly and the other derivatives and will swear by it?
Rossman...........No, I do not know of anyone swabbing their bore with Lock-Eze! After a good cleaning of my barrels I will run a patch with liquid moly (Mid-Way sells it) down the bore to sort of.... pre coat it.
