MUST SHARE- Moly coating trick

[DRNewcomb]

The question for me is not so much what the bullets look like going into the chamber but what they look like coming out the muzzle. The theory on the original molly coating method, using the small ball bearings as media, was that the hard steel balls peened the molly into the copper. That's just the theory I recall. I've never recovered and examined any shot bullets to give them a microscopic examination to tell you one way or the other.

Using this method the moly is still peened into the bullets, it's just that the bullets do it to each other in the container.
Steel shot and ceramic media were extremely messy.
I have recovered jackets from below steel targets and game, they still have the gunmetal color. Now if anyone thinks the rifleing in the barrel isn't cutting through the moly and into the jacket, they're mistaken.

It's not new. The process was written up in PS magazine about 10 years ago. I tried it a few times and could never justify the effort when checking the targets. It does make damn pretty bullets, though!

I tried this the other day. used my usual peanut butter jar and added 100 30 cal bullets plus twice the amt of moly. 4 hours in the vibrator and my result do not mirror orthers the moly was thin and i could still see the brass around the pressure ring. This was with my old jar which already has large amounts of moly dust. I am going to try today with a glass jar and 3x the amount of normal moly. I am thinking the slur was not concentrated enough.

As for the messed up batch i ran them in a dry mix 2 hours and they look very professional like they do when i run them dry most times

ypur upper pic of moly bullets..is abnormal, in my opinion. my dry, peened moly bullets look more like your lower pic.
so something i snot correct in your old process...
two
i do not see anyone doing or talking about waxing...
in the lapua test, 25% of the benefit came from the wax.....

HAVING SAID THAT
i am going to try wet moly the next time i do moly.
i have switched to HBN and will slowly migrate all my coating to that process.

nice thread

I have seen Hornady factory moly bullets that looks very similar to the top one.

BTW, MINE never looked that crappy when I did dry moly... HAHAHA!!!

I actually got these bullets from a guy on the forum and I recoated them with my process.

I NEVER NEVER NEVER got a finish like the wet when doing the dry.... and its so fast and easy. I need to make my video and put it on Youtube.

So i found about this thread a bit ago then i got a wild hair and gave it a shot. But i think i am at a 80% solution for coating bullets using the WET METHOD.

I Used a old Viatimin bottle

3 teaspns of lyman super moly

80 or so 208 amax's

they can out with some rough spots on the moly, anything i can do to avoid this?

I am trying the water method with moly but have found some tips plugged with moly and when I cleaned the tip I found water behind the moly. Am I doing something wrong? I am not sure how much space is available in the jacket and wonder if this will change the bullet flight?

A very interesting point. Don't some VLD bullets have a hollow behind the tip (meplat)? If that were to fill with water couldn't it play havoc with accuracy? I'd have to say, "The proof of the pudding.....". It's not really important how they look. What's important is what happens in the barrel and downrange. It would be interesting to snag some bullets, that have been coated by different methods, downrange and see if there's any difference.

(n.b. I didn't realize that this is a very old thread.)

Eric, once I reclaim most of the moly with a sieve I immediately transfer the bullets to a container of water to keep them wet while I dry and polish a few at a time. Moly air dries too quickly to try to polish any large amount at once.

 

[eric32]

What do you use to polish them?

What is the effect if the bullets are not completely polished ?

Thanks for the tip, I was wondering how some were pretty, some were pretty ugly. bingo
As for the extra moly, I don't see how it could effect bullet flight, may be wrong, the tips plugged, no big deal either. Or am I wrong?

 

[Immike]

What do you use to polish them?

Paper towel them dry and put them on a dry cloth such as a old T-shirt then fold it over and give them a good rub down. I don't recommend using your wife's favorite towels.

 

[eric32]

thanks for the tip

going to try and polish some and leave some ugly and see if its going to affect any accuracy or ES or SD numbers


***The reason the bullets came out with those different strips of moly on the is due to i had too many in one can so i split them in half between two bottles and it came out looking great.

pour them on into a laundry bag with holes put the water back into the original bottles then tossed them onto a old t-shirt rubbed them down and shiny as can be.

eric32 - are you using a plastic vitamin bottle? I'm getting ready to start moly coating again and I wanted to try the wet method this time.


Thanks!

eric glad you got it figured out. Should shoot me an email with some pic of the loaded rounds you are going to test

Thanks!

yes i did use them for the frist patch, but i am going to swtich to hogdon type 1lb bottles for more room for the 100 bullets per bottle.

eric glad you got it figured out. Should shoot me an email with some pic of the loaded rounds you are going to test

ill send some pics your way this afternoon

Hi guys I tried this method tonight and had one bottle turn out great results. But the other bottle the Molly did not stick. I tumbled for 3 hr. I have put it back in now so see how it go's with the same water.

Any thoughts ?

50 in each bottle of 6mm 105gr Hybrid

It's been mentioned before but bears repeating on this aging thread. Make SURE you degrease you bullets well before applying anything, I wash mine in hot water and Dawn, letting them sit to absorb the heat. IME, the warmer. cleaner bullets take the wet moly process the best, VERY uniform , just have to buff them quick as they dry. I put an old towel down on the bench and then use another towel on top of them to roll them around for 2 mins. Done.

 

[Caska]

Cleaned them prior with white spirits. This batch just dose not want to take. Will try some more tonight
