moly-coated

[mahi32084]

I just purchased my first 1911 (kimber pro carry II ss). I've converted from my glock days now to 1911's. So i decided to start loading my own ammo. I purchased a dillon sdb and have loaded about 700 rounds so far no problem w/ any of them. i'm loading 5.0 grains of 231 and using a moly-coated 230 gr. round nose. I haven't heard much about moly-coated in handgun's but i load some moly's for benchrest shooting my rifles. Anybody have any info on moly's for handgun?

I've been using 200gr & 155gr Precision moly in my Para 16.40. They are accurate and don't leave much residue in the barrel. I've used Win 231, Bullseye, N340, N320 and Titegroup. Seems to work best with the N320 although the Titegroup is good too. These are the only Moly bullets that I've used.
I started with the recommended load for cast bullets and worked from there.

I have heard moly coated bullets are a no-no especially in benchrest shooting. Not to disagree with you but I posed the same question to a Sierra tech and he told me to stick with copper jacked bullets. It was several years ago and I cannot remember his answer entirely so instead of a chance of posting incorrect info their number is 1 800 223 8799. Welcome to the forum.

If you go to the web sites there is a lot of info.
In the last few months I have been shooting both of these, mostly Precision, and like the advantages over lead. I have pushed them with TG, Bullseye, and Clays. The 230gr. ahead of 3.9grs of Clays so far has been the most accurate, but I am stil working-up loads. Hope this helps

That's because the common moly coated bullets were coated with "rifle" moly which is too abrasive for handguns, esp. SS barrels of such. The moly-disulphide coatings Master Blaster uses is proprietary and is less wear than FMJ. It is the only thing that goes down the tube of the 1991 Ultimate Stainless GCNM. It does not wear the rifling and does not foul the barrel.

I can load this round at the minimun recommended load for LRN (or 10% less) and it is a pleasure to shoot, esp. for my wife.

I understand but I primarily shoot 185gr and 200gr LSWC in my 1911s and use only Sierra Matchking bullets in my rifles (168gr Matchking mostly) and I do not think they make a moly disulphide bullet. Also I have heard that the moly coated bullets will imbed the moly disulphide compound into the lands and grooves (much like teflon will) and that can cause problems if you go back to FMJ. Copper is much softer then the steel barrels are made so I am not convinced it is an advantage to use moly coated bullets. I could be wrong though it has happened before.

Do not confuse moly coated copper jacketed bullets (commonly used with rifles) with moly-disulphide coated lead... Lead is softer than copper and the Moly-disulphide is a lubricant. So much so that the loads can be significantly lighter and acheive the same velocity.

I appreciate all the info. What i'm shooting is definitely not the "rifle" moly-coated it's specifically for handguns, i believe it's the master blaster. I've shot about 700 rounds now and have found them to be sooo much more accurate than any factory load. But the real reason i wanted to use them was to keep the barrel a little cleaner. Thanks again guys!

I've been using the MB exclusively in my GCNM with great results so far. I have spent some significant time with the president of the company discussing the details of the coating and the suitability of the application... There are some other threads discussing details AFAIK...

Contact them directly if you have any conserns, they are easy to talk to.

Definitely do not confuse the polymer coated bullets from Precision and Masterblasters with moly-coated, jacketed rifle bullets. I think Masterblasters claims twelve ingredients in their coating, only one of which is molybdenum disulfide.
