Why not moly coated bullets?

[glockky]

When i was working up a load for my encore pro hunter in 223 it was a struggle,until i

bought some 55 grain moly coated v max's which shot great. This was a few

years back but since i have joined THR I couldnt help but notice that most seem

to not like them. I have even read where people tried to remove the coating,

just wandering exactly what the reasoning for this was i have shot alot of them

through my gun with no problems?

I've read all the stories about moly and don't know whether or not to believe them....I do know that I have been loading 55 gr V-Max's in my .22-250 for years and it shoots nice tight groups with them. Yeah, I've read once you use moly you can't go back. That has not by my experience. I've also loaded plain copper V-Max's after using moly and got the same groupings.

Yeah, I've read once you use moly you can't go back.

You can remove the molly from the barrel, it just takes a lot of work.

 

[glockky]

Well I dont guess i have to worry then, because I have no desire not to shoot moly coated bullets. I mean my encore 223 shoots 5 shot groups just over 1/4" just wandering if there were any long term affects to the barrel.

I've read once you use moly you can't go back. That has not by my experience.

Nor mine. I've shot considerably better groups with my POF P308 after switching from moly to copper. So much for not being able to switch back.

My experience with molly coated bullets is only with two rifles that are used exclusively for across the course competition. I have not experienced transition problems associated with coated and non-coated bullets. My cleaning method is simplistic patches soaked thru with KANO-KOIL. The major difference is in powder charge weights between coated and non-coated bullet loadings.

 

[glockky]

My books show no differance and I have the new hornady reloading manual

Moly bullets and the resultant barrel coating is slipperyer than a non-coated bullet / barrel. Hence lower pressures and velocities with the same powder charge as non coated. You would up the powder charge to get the velocities back up.
The plus side of this complex load working is in some cases much higher velocities with reduced pressure signs.


There are two camps on the moly thing. those that do and those that don't. There have for as long as I can remember been arguments for and against.
One of the against was that Moly is somewhat hygroscopic.(Attracts Moisture)
There was a response that there was a contamination of iron in the sample that attracted the moisture. I never had any of the issues of rust in my coated barrels.

I was a user until a couple years ago and have switched over to HBN. Much Gooder.

I've been wanting to try them for every but the hype has been extreme. I noticed that Barns deleted them form their production line which made me that more shy of trying them. According to some, the build up causes higher pressures. But I think I'm going to eventually give them a try. I have a nicely seasoned 700 in 7mm rem. mag. that already shoots sub MOA groups, but if they have the potential to slow down barrel wear it would be worth while to shoot them.

I have an old military 30-06 and shooting a box (100) of Moly bullets actually helped it's accuracy. I'm guessing the light Moly coating inside the barrel smoothed it out or whatever it did, I like the results...

 

[glockky]

Well like I said they shoot great in my gun I kind of stumbled onto them trying to find something that would shoot. I was about ready to get rid of the gun until I went with the moly now I couldnt be happier.

I use Bear Creek moly bullets for 38 Spl, 9mm & 44-40.

I'm not real experienced with this but so far I'm happy with the results. Although when I'm pointing the 44-40 at something, it's usually safe from damage but I think that's the gun not the bullets.

I've switch between molly and copper on the 9mm and haven't seen any issues.

I would like a little more definitive information on this though as I REALLY like loading these things. That and they are pretty inexpensive if you buy them right.

I shot regular bullets out of my .223 rifle, then reloaded a couple of boxes of moly, they shot well also, not any big difference I could ascertain. When these bullets were shot up, I went back to my regular bullets, Hornady, I can now see a better performance after using the moly's, barrel fairies maybe? The accuracy has improved considerably, shot a .366 MOA last time at the range, maybe a lot of good life in that old 788 Rem. yet!

 

[wingman]

I had barrel pitting on a gun using moly replaced barrel never used moly again, could have been something unusual with my firearm however I seen no improvement when using so why do it.

There have for as long as I can remember been arguments for and against.
One of the against was that Moly is somewhat hygroscopic.

Given that the majority of my shooting is Black Powder and I live in an arid part of the country, any hygroscopic qualities of moly lubed bullets must be minor in comparison to Black Powder residue. By the way, I ONLY use moly bullets for smokeless.

moly coating

Go to Varmit Al's site he has a very educational article on moly coating.

Very informative regarding the moly bullets and possible problems. It doesn't sound like it's anything to be worried about as long as you take proper care of your gun. The fact that the Kroil appeared to prevent barrel corrosion when applied onto the moly lube left behind is a good sign.

I'm going to continue to use moly lubed bullets in both blued and stainless barrels.

 

[JoelSteinbach]

I shoot only moly coated bullets in all of my bench rest guns, I have found a slight increase in velocity as well as an easy clean up job. I have been tumble coating my bullets for about 13 years, the down side is your hands get filthy while you are loading.

 

[W.E.G.]

I moly-koted a bazillion or so bullets back when the craze first hit.

That moly dust likes to seep out of the tumbler and get on EVERYTHING.

Even the baby was moly-koted by the time I finished that mess.

I never want to clean up a mess like that again.
I sold my moly kit after that.

I'm still using up those bullets I koted.

The baby is about to graduate college.

I've had nothing but good luck shooting moly bullets (Hornady IIRC) in my bench rifles. Nice groups, found a powder and charge weight my gun likes, and I'm a happy camper. They will get you an odd look from someone that doesn't reload or a once-a-year shooter. I tell people they are "shadow tracers", some actually believe me.
