I thought the Moly Craze had pretty much run it's course back on the mid 2000's. I think it was really created and pushed by a very prominant Bullet Maker so they could charge a dollar more per 100 bullets.
I went through it. I tried to convince myself it was worth something, but I finally came to the conclusion that the best thing to do to premium Benchrest Bullets was just shoot them.
jackie,
if you were thinking sierra, they said it was hocus pocus, but did them to supply customer demand.
european testing says it works...."shoot the same longer" with some increase in bbl life. test was 6.5x55.
Harold Vaughn looked into 5 supposed benefits of Moly in "Rifle Accuracy Facts" - he tested four of them and found no noticeable advantage with Moly. The fifth claim was increased barrel life and he allowed that that claim might pan out, but testing such would be too onerous.

I've been shooting bullets coated with WS2 (titanium sulfide, I think( sometimes called DANZAC) for 12-13 years. I started with prairie dog ammo and now use it in all UBR matches. I would not use Moly due to it's reputation for building on itself and attracting moisture. I have never experienced a problem with WS2. As far as I can tell it doesn't enhance accuracy. But it does appear to reduce the need to clean so often. Once in a while I will clean between yardages, but usually I will shoot an entire agg (120-140 rounds) and clean the next morning. I tried it both ways (cleaning after every replay and not cleaning until after the match). I've seen no difference in accuracy. Matter of fact, I tend to shoot better @ 200 yards (2nd yardage) than 100, but that's probably just me. I use Patch Out with Accelerator for of my cleaning, the exception being that about once per season I will clean with Rem Clean. I have come to believe that my barrels may last a little longer, but wouldn't swear to it. I did try Boron Nitride for one season, but the bullets were difficult to pick up ( very slick) and I could detect no difference in accuracy. Most of the folks I compete with clean after every replay. I am probably the only one who doesn't. I win my share of matches. As Casey Stengle once said "you could look it up".

DITTO this . . . well, except that WS2 is tungsten disulfide . . . and, that since the craze began, way back when (?), I have stayed with the "moly" stuff, with similar experiences and beliefs. Although, it has caused me to win and to lose, so have other things. RG
