Moly coating

[simong]

Hello peeps,

Appologies if this has been covered elsewhere but a couple of questions have formed in my poor little brain :

Are there any benefits to coating copper jacketed bullets ?
Presuming that the moly coating stuff is a powder? a bit like graphite ? where do I get some and how easy is it for a simple Greek to make slippery pointy things ?

Have you thought about Hexagonal Boron Nitride instead of Moly?

Its cleaner, gives same benefits and apparently suffers none of the drawbacks such as the potential to attract moisture.

I am experimenting but results and easy application looking good.

Thanks for that.
I'm only just starting to investigate coating fmj's and had only heard of Moly.
Is this Boron easily obtainable, and how much might this add costwise per round ( or batch) please ?

I think that I need to research this coating business a bit more especially now there are options....

Thanks again for heads up

Moly is used for reducing pressure so you can run a case closer to capacity and/or reduce muzzle velocity. Moly is a lot cheaper than Hexagonal Boron Nitride however it is also filthy stuff to use. We Moly coat the bullets used in Christel's 22-6,5x47 using a Lyman system, so 3 hours with ceramic media then swap over to normal media for 5 minutes to remove the surplus Moly, the results are very good however I always end up covered in the stuff.

I stock both the tumbler and Moly kit and the Moly kit only if you get stuck The full kit is just over GBP92 and the Moly kit less tumbler is just over GBP46 (From memory) both are plus postage. Both include everything you need including two bowls, ceramic media, cleaning media and enough Moly powder to last you a lifetime. I use a cheap electric timer on our system so it shuts down at the right time and about the only other thing worth adding is a sieve, I built mine with some very cheap plastic bowls with lots of holes drilled in them.

What are you trying to achieve by using molly? I would do your research first as I think it's a bit of a one way ticket, once you have started it's a devil of a job to remove the molly coating from the barrel. I think the idea is beginning to fall out of fashion.

Why clean the barrel to remove the moly coating? I never do, all it gets when back from a shoot is a few patches with some methylated spirit and then an oily patch.

It is fully cleaned at around 110 shots or when accuracy drops slightly, three foulers through it and it is ready for the next 100

"What are you trying to achieve by using molly?" Very important question. I am playing with Sierra 220's in my match rifle; a look at the Sierra re-loading manual shows that they do not list the 220 grain bullet for use in the 308. However, a careful approach, mollying the bullets in order to flatten the pressure curve a little, has produced sensible results.

Hi Peeps,

Obviously the devil has made work for an idle brain ( I must worry more about work and stop thinking about shooting !)

My initial thought was, as to wether or not moly coating would help the round slide down the barrel thereby decreasing wear and in my iggerence thought that if there was less resistance then I would get slightly higher speeds for the same charge.
Seems to me now that there may be a slight wear reduction but also less speed.
Methinks that I might just leave well enough alone for the present and concentrate on my technique rather than the technical ( I'm still learning with the rifle ) and after all its only a playtime 308.

As allways thanks for the input folks.

I bought a pound at about £72 BUT it will do tens and tens of thousands of rounds..... I never expect to have to buy more in this lifetime.

I am after extending barrel life as a priority and lengthening round count between cleaning.

Tons on the web and I can send you supplier URL if required.

Dabbled with moly coating years ago and found it gave me no benefits.

Like many of the shooting chimeras that surround us it seemed to me a solution looking for a problem to fix.

It took me ages to get my barrel clean of the stuff and settled down again when I stopped using the damned stuff
