moly bullets faster?

[mortman]

Hi,

Well, I am going to try this again. Still looking for a more definitive answer.
Moly bullet makers have claimed that molys fly faster (higher velocity than standard lead given the same powder charge and gun).

This would be useful for making the power floor ( http://www.ccidpa.org/idpa-power.html ) in competition i.e.: lower recoil, less muzzle climb.

So what do you know, is this true?

Thanks,
m.

No I was told they actually come out slower. The only good thing about molly is people shoot up to 10000+ rounds of it to polish up the barrel and make it easier to clean after words. That's the only up side I have been told about them.

But if your shooting Molly don't switch to normal bulets for if you do I heard it makes it 10x harder to clean your barrel after words due to the powder now being mixed with the Molly coating in the barrel. I was told they have no ballistic advantage at all. Just makes guns easier to clean if your break your barrel in with them.

not in my experience

Hi,
Used molys when lead was hard to get (Masterblasters, now defunct, always seemed to be supplied).

From my experience, moly ain't easier to clean (.45 ACP, 1911). And the crap is messy as in all over your fingers in the reloading process.

So, there must be a reason to use them, but if not faster than conventional lead, I'm stumped here.

My experience with moly 45 ACP is completely opposite from mortman and CK 32. I have used plenty of Precision Bullets and Bear Creek with great results. They feed great, no leading even at higher velocities (200gr SWC@850+FPS). Switching from moly to lead or jacketed is no issue at all. The moly is like a hard gray paint, doesn't get on your fingers or the bore. The bullets don't need lubing in the grooves so there is way less smoke than regular cast lead. Depending on the maker the price is somewhere between hardcast and FMJ so I view it as a value. But this is just my experience.

Bear Creek with great results

Good to know thanks! I just reloaded a bunch in .45acp.

[mortman]

Bear Creeks okay on the cleanliness issue.

But anybody think molys are faster? Chronographed similar loads comparatively?

used em in pistols and even coated some jacketed rifle bullets. Can't say what they did for anything but they didn't hurt anything.

I'm not giving you a hard time, unless you provoke it, but please consider the logic behind your assumption: (to start you in the right direction; powder is used whether or not bullets are molly).

I only shot about 500 rounds of bear creek 230 gr rn in my 1911 and I didn't have any mess to clean up.

He's saying that the powder residue could get mixed into the moly coating left behind in the barrel...

I've heard that switching between moly and regular jacketed bullets is a non-issue in short barreled pistols. It's more of an issue in long barreled precision rifles, in which the cleanliness and condition of your bore determines how precise your next shot will be. I'm talking about the guys that clean their barrels every one or two shots on the firing line for maximum precision. I honestly believe that out of a short barreled pistol, it won't make a bit of difference at all, as I've shot both FMJ, plated, AND moly coated bullets through my 1911 without issue.

Also, I suppose it should be known that bullets like Bear Creek "moly" bullets aren't exactly the same kind of moly coated bullets you would use in a precision rifle. They're coated with more of a "poly" coat, in which moly disulfide is one of the many ingredients that go into the lube, but certainly not all of it. Watch a video on actually moly coating bullets, and you'll see that the process and finished product is completely different. True moly disulfide powder gets EVERYWHERE.

For rifles, from what I have been told, the pressures are a little lower with the moly coating and you can push them a little faster. Like I said, what I have been told. But a reloader I know swears by them, and molys every bullet before he loads it.

I'll throw in my .02 cents since I've shot over 60,000+ rounds of Bear Creek through my G34.. I havent' shot "straight" lead through it, but I've also run Montana Gold and ZERO's (both FMJs and JHPs) using the same amount of powder. I dont' have (ie cant' find) the chrono data right now, but I do remember the the moly's shooting somewhat faster for the same amount of powder and bullet weight. The delta, however, was very, very minimal- something like on the order of 30-50 FPS when using moly vs a jacketed bullet.

If you're trying to gain an advantage using moly to reduce recoil, you're going in a completely wrong direction. The guys who compete and do well aren't winning because there guns are recoiling softer than yours.

I only have rifle experience with moly coated bullets but I loaded several hundred rounds of 22-250 Hornady that were Molly coated and regular they were the same bullet just one was moly coated. I shot them through the same rifle on the same day. They were almost exactly the same. The molys were just a bit faster may be 20 to 40 FPS faster. The moly coating did rub off so it was kind of messy. If you are planning on allot of rounds in a short period of time were the barrel is getting hot then the molys would work better than the standard bullet (less friction).

All cartridges use gun powder, so wouldn't the gun powder from the moly coated bullet cartridge foul the moly coated barrel?

I think that is what otto was getting at.


The only thing I have noticed with moly coated bullets is that my wallet is a bit lighter.

That would be the case with any lead boolit vs a jacketed one, wouldn't it?

The deal with moly I've always seen was that it was cleaner than plain lead. Can't say I've ever seen claims of faster pistol bullets.
