Moly ?

[FroggyOne2]

The load that I have been shooting @ 1K with the 223 is only going about 2785 fps. So you really don't need blistering fast speed, BUT, it is nice to have.

I was shooting 80gr JLKs at 2850 or above. My goal is to be above Mach 1.2 at the target.

I will try the Dawn dish soap trick on molyed bullets and see if it comes off,

that what I'm after is 1.2 mach at 1000, I'm falling short buy about 75 yards. i can get there but it eats up my brass as you stated Bayou Shooter.

Thanks you guys for getting me set strait

Well, this was over 4 years ago, but my load was 26.0gr Varget in a Winchester case topped by an 80gr JLK. Now, I load 24.0 Varget for 300 yards.

we will have to disagree on this one...moly builds up..the length of the bb.
a lot of guys also do not know what they are doing .
did you wax your bullets ??
25% of the moly benefit comes from the WAX.

go ask lapua about moly...they have data on thier site.

Moly does not build up. There lots of guys who go back and forth between naked and coated.

Sorry for the delay in coming back here.

I have been using moly coated in my first F-TR rifle because it is a .223 Remington with a 26 inch Krieger barrel and I had found a node at a tic over max load. I wanted to decrease the pressure because it was beating up the brass. So, I started moly coating the bullets increasing the load a little bit more and the brass was not getting beaten up as much.

I do not subscribe to the theory that barrels last longer because you shoot moly coated bullets.

I am not so sure if moly coated bullets allow you to shoot accurately with less cleaning. I never clean during a match anyway.

I do know that moly-coating is a pain and it's an extra step and it creates issues in the barrel of which you must be aware. Also, once you go moly, you can't really go naked in the same barrel, regardless of how much you scrub.

My next two F-TR rifles have never seen a moly-coated bullet. I switched to .308 WInchester, increased the barrel length to 32 and was able to find nice accuracy nodes just below maximim load at a velocity that was greater than the minimum I required. Now my .223 only shoots 300yard matches and I don't need the supermax velocity I needed for 1000 yards.

Not true at all! I have switched back and forth for years, it requires a little more cleaning but not much, now I might agree if you was using it in a rough factory or wore out barrel, my son's 6brx Krieger has over 3K rounds through it all shot with 107 SMK's mollied and my oldest son just used it in a 1000 yard br match, it was his first match ever and he shot a 6.9" 10 shot group with it, not gonna win any medals with it but he was happy and so was I, then I stripped the moly out of it and been shooting naked 87 grain v-max bullets at ground hogs out to about 900 yards with more hits then misses, I never wax the molly bullets anymore but I clean more then normal and haven't ever noticed a degrade in accuracy or build up.

Wayne,

My old 223 I am shooting, I clean it every 150 rounds or so, that one is using dry bullets. I suspect I will treat the new 223 with the moly'd bullets the same way. As for the new 22BR, prob half that many rounds.

That would sound about right to me, I ran it for years in my 22-250's and probably was able to double the amount of shots over naked bullet before cleaning had to be performed but I usually cleaned them when accuracy started to fall off and 150 or so sounds about right to me, of course it would depend on the barrel I suppose.

Thanks for the feed back on that Wayne!

 

[ar10ar15man]

the typical reason a moly bbl's accuracy starts to fall off is carbon build up..
this is not typical of neked bbl's but a side effect of the insulating property of the moly layer.
start your cleaning with a carbon buster on patches..

Ive used moly in my AR, for quite some time that barrel if very forgiving never a problem there. I just about threw out my last bench gun over moly, if you are going to push presures towards the hot side,then be careful after cleaning and use a reduced load to refoul barrel,if you try to do all this in a seven minute sighter time and re zero with a max load once you think you have ample fouling,and now your barrel is smoking hot then the match starts. I hate to bable however i just like to be calm when competing and not burn up extra ammo thats scarce to get now.That was the easy part,when we checked the inside of the throat with a scope my 500 round barrel looked so heat cracked i ordered a new barrel the next day, Sorry no more moly for me.

That's a great point swed6.5, didn't even think about firing after a cleaning, and this load would be quite hot on the naked side.
