Moly - who still uses it??

[Tim N]

Hi All
I recently loaded some rounds for my 6 Dasher that were decided on 5 yrs ago.
At that time moly was popular so rather than change anything a friend mollied some more projectiles for me and the next batch are ready to go.
Just wondering if many still moly bullets(or any other coating)?

I've used moly for about 15 years, abandoned it for about a year recently, but now back to it again. Reasons, minimises copper fouling in tight twist barrels, smooths out bullet seating force.

I would be reckoning for the reasons u describe Alan it would/could help lots but I suspect with many other ‘normal’ barrels it won’t provide any gains and will instead introduce other potentially detrimental variables and dynamics. A barrel that for whatever reason wants to foul more than is desirable could be a good candidate for moly too, as with using a bullet with a relatively long bearing surface.

Otherwise just clean your barrel properly at the end of the days shooting, or maybe it will survive two days shooting between cleans. Then check with a borescope to make sure u have in fact cleaned it sufficiently. Then fire a fouler or two and ya back in the middle. Hopefully !

I believe a few top shooters use moly but remember those shooters have tons of knowledge and experience so can manage any problems and variables that may appear.

Does using a medium of whatever sort to help uniform bullet grip, or bullet release forces, help ??? Lord knows but I begin to think that theory is just another one from the “feel good” file.

My current 284AI FO barrel copper fouls minimally ( using 2209 and 180 hybrids ) but it gets blacker and blacker as the round count climbs throughout the breech end section. And I mean a hard black glazed-on coating that does NOT come out with ‘normal’ cleaning and THAT is something that needs monitoring, way ahead of any coppering problems IMO. But that too can be managed. Moly could help there too ? I've only tried it once on a barrel that was an inconsistent pig and it carried on being the same pig with the moly too.

I still use moly (and 1 barrel on WS2) in FTR. It's worth about a grain of powder. (ie if you add moly you need to add a gran of powder to get the same velocity)
Its also an effective neck lube.
I'll shoot about 300 rounds between cleans and then jb the barrel. A wipe through with a patch with moly suspended in alcohol puts the gun straight back on line.

I believe moly does offer lubricating properties in the barrel, hence the velocity drop and lack of copper fouling. I also suspect its presence on the barrel surface reduces carbon fouling because the carbon has nothing to bond to. It bonds to the surface layer of moly, which does not bond to the barrel so just gets removed as you go. Just a theory but one that keeps me happy.

I used it in a 6 m PPC ,A REM 700 ,Hart barrel would go .5 @ 200yds ,always cleaned the same as a non moly , ie Sweets and Sweets Oil.after every shoot, The present owner says it still goes just as good now.

I still use it in barrels which need it.
If a barrel cant get through a days shooting without cleaning, due to copper build up, then I will certainly try moly and check again if it is now able to go a full days shooting without losing accuracy.
If a barrel is able to shoot for a full day, then I usually wont bother with moly, as I prefer to leave all barrels soaking in solvent overnight anyway regardless of whether I am running moly or bare.
Lately all of my barrels have nor needed moly, but a few of my older 6mm barrels do.

Tell me this please : is there a solvent on the planet that will get under that "ceramic carbon layer" and make it let go so I don't need to cut it away with abrasives ?

Just on a side note, what do you guys use to apply jb paste? An old brush? Cloth on a jag? Cloth on an old brush?
