To Molly or Not to Molly.....

That is the question.....
What are the REAL advantages to molly coated bullets....
I have read that it lessens the friction in the barrel extending barrel life...but does it...and are there any other advantages and what are the draw backs, if any, or does it really matter...or is it just up to the individual. Is there any different Ballistic coefficient between the two which would be noticeable...The reason for my inquiries is that I have a chance to pick up some molly coated hornady 168gr A-Max and some 55gr V-max and am wondering the difference and any possible affects on my guns...

Armalite Tech Dept recommends molly coated 168gr projectiles for all their rifles. I

I am just a casual shooter and I reload. The other day I fired some hornady 168 grain amax and then some hornady 168 grain amax mollycoated bullets at 200 yd from an ar10t being pushed by imr 4895, 41.2gr.
The groups got tighter and smaller with the molly coated bullets. I was surprised. best 5 shot group was 2.4 in with amax and 2.1 inches with the moly. Fired 50 rounds of the amax before switching to the molly. fired 20 rds of the mollycoated. It does take me a clip or two to settle in as I don't shoot often enough, and the warmed up barrel for the molly coated could have been a factor too.
Others on this forum could address those possible issues more expertly than me

I have read that Molly will attract moisture, so if you leave it in your barrel, you might get rust. I don't know if it is true or not.....

I have shot moly in the past, but didn't find it to be any better accuracy wise.

As for barrel life, I would suspect that in a .308 it's not going to add that much more life. I know guys who are shooting barrels with over 5000 rounds through them and they are still tack drivers. On a .300WM or something similar, you will probably notice a difference.

It wouldn't hurt to try some out.

My experience.

If you can get them for the same price they're ok... no better than bare copper. Moly is short for molybdenum di sulfide, (or some such silly crap as that, it's NOT plastic) and was once thought to be the holy grail.

It never helped (or hurt) my scores. I did notice that it took an extra 1/2 grain or more of powder to get the same velocities... hence the friction reduction. Your barrel still needs cleaning, it's another step if you make your own and it will not improve accuracy...tests prove it. Barrel life is more a function of throat erosion and it don't do squat for that. That's burning powder in your throat.

I can see where it might lower barrel temperatures due to lower friction for less bullet drift due to barrel heating for rapid fire. It does make cleaning marginally easier.

Another snake oil if you ask me.

Well guys thanks for the input, keep it coming. I was wondering about them because my local dealer has some in stock and it would save me from ordering the standard A max or V max bullets to reload certain rounds...
Might have to give them a try...but I might wait as well, do some more research...maybe call Hornady...


Easy M....don't get flustered....that is why we post things so we can get the info right...Right teach....Jeez those marines getting you bunched...LOL :lol: Just Ribbing you Teach... :woohoo: :silly:

I'm set to reload with moly but haven't yet. I believe my 22-250 will benifit the most but will try with 308 also.
Here is a link with good info.

The MSDS sheet on the new 55gal drum of molly didn't list any poly Its 99.5 molly, and we were going to use an additive and are wondering what poly they were using is. Thats why the question.MSH
