Cleaning solvents to clean Moly barrels(KROIL)

[Trevor60]

To continue were to get cleaning supplies. Would anyone know were to get Kroil. I can’t seem to find it anywhere other then on the Internet out of the US. I am not sure they can ship that up here.

I shoot moly and would like to follow this cleaning regime.

The below process is from Berger Bullets

1. How do I clean my rifle when using Moly Coated bullets?

The best procedure for cleaning when using Moly coated bullets is as follows:

1. Push one wet patch with Kroil Oil through the barrel.
2. Repeat Step 1.
3. Push one dry patch through the barrel.
4. Repeat Step 3.
5. Push one wet patch with Butch's Bore Shine through the barrel.
6. Repeat Step 5.
7. Let soak for five to ten minutes.
8. Push one dry patch through the barrel.
9. Repeat Step 8.
10. Short stroke one patch with USP Bore Paste through the barrel.
11. Push one patch wet with Kroil Oil through the barrel.
12. Repeat Step 11 twice.
13. Push one dry patch through the barrel.
14. Repeat Step 13 three times.
15. Use bore scope or visually check muzzle to insure barrel is free from copper fouling.
16. If inspection shows copper fouling still in barrel, repeat Steps 10 through 14.
17. If rifle is to be placed in storage, push one patch wet with a good grade of gun oil through the barrel

Trevor,
Just shoot the moly bullets and forget about cleaning for a while. I went about 900 rounds then cleaned. I should have left it alone until the groups opened up. It took about 200 rounds to get it shooting back to less then 1/2 minute elevation. Starting again with a new barrel (couldn't make the TR weight with a new stock) so I will keep shooting it until the groups open, or the bullets don't fit down the barrel. I may not clean at all this year, or at least until after the DCRA.

Thanks Gentlmen.

Maynard. I am not able to get out shooting as often as i like so the rifle sits longer then i want. It more a piece of mind then anything else.

If you plan on using Kroil or any oil product to reduce risk of bore rust, I would suggest you reconsider your need for Moly.

Moly thrives on a moly fouled bore. When you clean excessively or put an oil in the bore, it can lead to serious headaches. At best, you will need fouling shots to reestablish the moly layer. Some use moly on a patch but don't like this method either. At least the products I used sucked....

I shoot moly ALOT but live in a very dry climate. I essentially don't clean my rifles until needed (loss of accuracy). I might run a dry patch or brush down the bore every now and then but that's it for the most part.

If you believe in cleaning your rifles often, moly will show no benefit and can actually degrade your accuracy (the first bunch of shots will be irratic until the moly layer is formed).

Like Barrel break ins, the Berger cleaning info really is there to satisfy those who want to read it. For anyone with experience with moly, the big benefit is that you don't need to clean for a very long time in most barrels.

Visible Copper fouling might not degrade accuracy at all. Depends on the barrel.

If you want to use moly, set up a drying system in your locker so that you don't need to oil the bore. Not a bad idea at any rate.

As you can see, abrasive cleaners is the best way to remove moly if you really must. JB is my choice.

Butch's bore shine can readily be replaced with any powder solvent. It is not a good copper solvent. If you must remove copper, then a strong ammonia based solvent like Barnes CR10 would be my choice or JB. Janitorial grade ammonia solution is the best product you can get and dirt cheap.

I have left the bore with moly in it, untouched from one season to the next
First sighter in the spring from 600 yards was a bull 5.

Oh I would like to add my breaking procedure with the new barrel was to shoot 11 rounds of moly at 25 yards at a zeroing target to find a 300 yard zero.

I have noticed with my current cleaning regiment with solvent and a light patch of oil my 1st shot is not near the point of aim. I will do as suggest and run a Dry patch through it and put it away.

Mystic I read a previous thread were you suggested janitorial ammonia but haven't had a chance to locate a local supply store to get some.

Bashaw Sports has Kroil also.

I use a Shooters Choice/Kroil mixture (2 parts SC to 1 part Kroil) for cleaning my Moly'd bore.I got this recipe from a U.S. Palma Team shooter.

When I have to clean, I run a final patch with Hoppes moly paste on it to re-coat the bore.Haven't had any problems doing this.

As advised, you don't clean Moly'd bores until accuracy goes away.I have gone 400 to 500 rounds between cleanings with no lose of accuracy.

SKBY.

We also stock Kroil An additional source is Century Sales.

I have been using moly for probably 4-5 years now with no concerns. I also borescope regularily.
