Moly your bore and action!!!

:D  This process greatly improves the accuracy,barrel life,and velocity. Best of all it is easy to do. First clean your bore( i use J-B Bore Bright) with a solvent of your choice. Then useing the aerosol spray type Moly(which you can find at most gunshops maybe even Brownell's) spray the Moly liberally on a patch,and place on a jag then run through the bore making sure to get it all coated. Repeat the coating process as needed. Don't worry about getting to much because the first few rounds you fire through it will iron out any excess. The same thing goes for your action whether it is bolt,semi-auto or pump. Now for breaking some old (bad) habits, as from now on you must not use a wire bore brush. It will take out all the Moly you just put in. Another thing is now you must use a solvent that is meant to remove powder and nothing else. Solvents that remove lead,and copper will strip out the Moly coating,and after the Moly you should not have any lead or copper fouling.After using the solvent do as usual and run a few dry patches through until clean then apply a light coat of oil. Following the previous maintenence/cleaning steps should give you excellent results,and you should only have to recoat your bore after 750 to 100 rounds. As cheap as this aerosol Moly is this is a really good deal. I found a can at my gunshop for $9. Hope this info is useful to anyone willing to try it.

I just use the moly bullets in my 223,anything that makes less friction = less vibration,less chamberpressure, sometimes better accurcey, less heat,and less wear.  It takes about 15 to 25 rds.of moly's to start it shooting good, and it'l take about the same of non moly's to take it out. I shoot about 80 rds. through it, run a few dry patch's through it until it comes out clean,and then I'm good for 80 more.  Digger

You may want to go to some of the other websites to see why a number of people are quitting on using 'moly'  (technical grade, I guess) for coating their projectiles.     It seems that some barrels are building up moly' like shotguns can build up plastic (?) and then moisture gets underneath and attacks the barrel!    Accuracy deteriorates all of a sudden and cannot be brought back.....

I use moly' extreme pressure grease to get moly' etched into the bore, but it's able to migrate, apparently, out of the grease to get into the steel.   Regular moly', from a couple of places I've read, including non-shooting sites, does not migrate or etch its way into the metal.    It has to be formulated with grease in order to work properly.      

Be careful with moly' is all I can say, until you know for sure which type will work for you.
Yet a little while and the wicked man shall be no more.   Though you mark his place he will not be there.   Ps. 37.

Some shooters seem to have the idea that when using Moly you don't have to clean your barrels much. That is wrong.

I have been using Moly for 6 or 7 years now and have never experienced any trouble with it. Moly works best when impact plating applied with steel shot in a tumbler. The spray on stuff applies too much and gunks up the barrel.

The system I use is was perfected by NECO, and it works perfect.
Many of the shortcut applications are just that and cause build up.

Regardless of Moly you need to remove the carbon from the bore and likely copper fouling. Moly works best in smooth bores.

To get Moly to impact plate properly on bullets they have to be free of any swaging lubricants. I shoot Bench Rest and use nothing but Moly coated bullets for that. I use it in all my hunting rifles, since I have all the materials and equipment.

I clean my barrel with a mix of Shooters Choice and Kroil. Swap first then
stroke with a brass brush swap again with solvent and then dry patch. This will not remove all the Moly. Before shooting again I use a brush wrapped with a patch and apply an oil/Moly mix to season the barrel again. The first fouling shot stays in the group using this method.

But cleaning you must, for heavy fouled bores and or rough bores the use of JB paste is recommended. Then season the bore again with the oil/Moly mix. It works, and it is not hear say.

Just finished breaking in a new Shilen 30BR barrel using 125gr Moly bullets, 15 rounds shoot and clean each round as above then a fouling shot, then the last four shots grouped into a bullet and a 1/2  or so?.

I don't think my new 25-06 H&R Ultra will do that good, but Moly it will shoot. Benefits are, less throat wear, easier cleaning, less pressure, more velocity, no trouble loading into the lands.
