I read this article a few months ago but finally got around to trying it out on 300 105 amax's. I have been shooting moly coated bullets through my 243AI since it was built, coating them myself.

I haven't shot any like this yet, but if nothing changes I think this is a far better way to coat the bullets than using the powder dry.

I will say that I used too much water and not enough moly on my first attempt and after 3 hours of tumbling it was a bunch of bullets in black water. I added a bunch more moly and let them run for another few hours. Turned out great. I dumped the water and bullets into a strainer and caught the water in a second jar to re use it later. I rinsed the bullets off and patted them dry. The moly coating stays on the bullet and will not come off on your hands.

If you moly coat and haven't tried this yet I say give it a go.
 
I find that shooting moly coated bullets means less cleaning. It also causes less pressure because of the slippery bullets, so you need to bump your load up about .5 gr in a .308 size case. I use the dry tumbler method of applying the moly, take about 2 hours. Use a big slotted kitchen spoon to take the bullets out of the tumbler and roll them on an old towel to remove the excess. Makes it a little cleaner when handling them when loading and when pulling them out of the box to shoot them.

If you start with a clean barrel, it may take up to 20 rounds for the barrel to get coated with moly and the groups to settle in. Then just keep shooting until the groups start to open up. I have gone over 800 rounds before cleaning and only cleaned then because I had a couple of big matches coming up. Clean the barrel with Kroil and some JB Paste followed by some foaming bore cleaner to remove the moly. I have never shot bare bullets over a moly coated barrel or shot moly bullets after bare bullets without cleaning.
 
I tried Moly coated bullets for a 3 month period back a couple of years.

Could not see any distinctive advantage over bare bullets, so I use my time for other reloading routines now.

There is a paper that was done by Norma I believe that they claim to have tested a few barrels and saw an increase in barrel life using moly. Is it true? I don't know I haven't shot out any barrels yet.
I went 800+ rounds in my 243 AI before the groups started to open up and I cleaned the bore, very little copper fouling. But this is also my first aftermarket barrel, so I don't know how much fouling there might have been if I wasn't using moly.

I always applied the moly dry until last night. I would tumble them for a few hours than shake the bullets out into a large tube sock and then tip it back and forth to polish off the excess moly, then dump the bullets back into their boxes.

The bullets I did in the water, the moly coating seems to be thinner and adhered to the bullet way better than it ever was when I did dry. It doesn't rub off on your hands when handling the bullets and is much harder to rub off if you rub the bullet on your jeans or something.

Just something I thought I would pass on for others to try. Here a couple quick pictures between the amax's I did last night and some 115 bergers that I have had sitting around that were done dry. The Bergers have been rolling around in that box for a while.
