Hello everyone,

I was wondering if anyone has any experience using either Moly coated bullets or Lubalox bullets. I have done a lot of research (I have found nothing here on PS and found a small amount in other places) but haven't really found any opinions stating if the coatings make that much more of a difference. I know what both were designed for and "supposed" to do as far as the manufactures claims, but just wanted to know if anyone has personally tried them. I will post the websites with the info I have found below.

How much is accuracy affected with Moly coated pullets? Does the coating make the barrel THAT much easier to clean? I am not lazy so I don't mind spending a little more time cleaning a barrel to ensure that it will last. And are the amount of rounds fired between Lubalox vs regular copper bullets that much greater?

Any and all advice is greatly appreciated.

This is principally a benchrest type question.

I think David Tubbs is marketing and hyping a new coating of boron nitride.

At one time in my life I shot the 6mm Barnes blue meanies and killed several deer with them. I found no difference in the final resting stage of the deer compared to 85 grain Speers without any coating. Rifle was a 240 Wby and the range was seldom more than 200 yards so 50 fps difference in screaming hyper velocity was not noticeable.

Cant say much about the coated bullets, but I am a great fan of the Barnes X and can say that the old ones, which made full contact with the bore left much more hard-to-clean copper residue than the new ones with bands around the bullet.

Thank you both for the input. I will probably stick to the plain old copper bullets like I have been.

Riflemans Journal has 4 articles dedicated to Moly coating. It is a good read.

My personal experience has been that it is something that is not worth the pursuit. Shooters can be a superstitous bunch when it comes to what matters, and how much it matters on some things.

Plain old copper jackets hold plenty of reccords in Palma and NRA prone competitions. Any advantage because of moly is more likely going to show up because of the shooters increased confidence, not because of the moly itself.

I have read about the moly coated bullets. Personally I don't like them as it
seem you can't remove the moly or go back to copper bullets.
I have also ask Douglas Barrel makers this very question. As I have a
30-06 Douglas Barrel xx with Springfield action that shoot very consistently
as long as I do my part.

One forum opinions here. http://www.thefirearmsforum.com/showthread.php?t=64428

The point to moly coating is that you don't want to, and can't completely remove it. The molydisulphide adheres to metal under temperature and pressure, actually melding into the pores of the metal. It is a lubricant and will smooth you barrel's surface, thus giving you a little more velocity for a given charge.

I've shot literally thousands of moly-coated 5.56 and 7.62 bullets. I've probably got 500-1000 175-grain Sierra Match Kings left.

Do they make a difference as far as accuracy or precision? Not that I can tell.

Conventional wisdom (as far as precision and competition goes) was they were supposed to extend the number of precision groups you could shoot between cleanings.

Moly contributed to less jacket distortion (by the rifling) and gave smoother laminar airflow over the bullet profile while in flight.

The price difference was around $2-10 for 500 bullets (as reloading components). You would need a little more powder to get the same velocity as standard jacketed bullets because slicker moly bullets had less drag in the barrel.

They are less popular as competitive shooters found they do not give a marked advantage over standard bullets for the cost. You may still be able to get them as benchrest guys find they do give them a slight advantage (these are fellas trying to put five and ten shots into one single hole).
