Any special barrel break in procedure for shooting strictly moly bullets?

I recently purchased a Ruger #1 in .22-250 that I haven't shot yet. I would like to shoot nothing but moly coated bullets as I've heard not to swith back between moly and un-coated.
Is there any special break in procedure that I need to follow or is it basically like breaking in any other barrel?
I will probably stick with the Hornady Varmint Express until I get a reloading press.
 
This might be a can o'worms...

Be sure to clean the bore thoroughly before starting.
I break in my barrels with moly bullets, since that's what I shoot in 'em. Some folks say not to use coated bullets in the break-in, as you need the higher friction to get proper break-in. This is a point worth considering, especially with a factory barrel... Use JB to polish up the bore as much as possible first, then lots of patches and solvent to get it all out.
Be patient, and wear out a bore brush or two in the process.:D
 
Good Guy, To use moly in a nice new Ruger #1 is questionable. Have you ever used it before? Do you live in the desert? Does your gun ever come into a humid environment? Do you clean the moly residue thoroughly after each shooting session? There are more reasons not to use moly then there are to use it. Good Luck.
 
Here we go again...

Try the moly yourself, then come to your own conclusions. If you don't like the stuff, you can clean your bore of it and be done with it.


The reason I state the above is because many of us have actually experienced benefits with moly that outweigh the disadvantages. I wouldn't endorse it if it didn't work for me, I had my doubts about it, and tried it with some trepidation. I ain't getting paid as a poster child for the technique by Midway or Neko. I now run the stuff in the 24 different calibers I reload for, and it's helped extend an expensive Krieger barrel's life, and kept copper fouling of a 6.5-06 to an absolute minimum. As I finish my new 6.5-300 Weatherby Magnum project, I will run nothing but moly-coated Sierra MatchKings, I trust the stuff that much, especially at those hyper velocities.


And if folks simply refer to the countless gun rag articles discussing the pros and cons of the technique, without doing some hands-on, a lot of neat stuff would never get out there on the benches where the pudding congeals. It'd be like saying that there's no reason for anything other than the .270 Winchester, because all you ever did was read Jim Carmichael.


Read back through the archives here for the moly coated bullet discussions, too. This continues a post I started there earlier.

Yikes! I don't remember posting this thread.

Say GoodGuy, no offense but... how's about picking another user name? Things could get a little confusing around here otherwise.

Thanks, the original Good Guy :D
 
Hey! 2 Good Guys. I'll try to figure out how to change it. I'm GoodGuy on like 3 other boards, and I didn't realize their was 2 of us. Yes, your'e right, it could get a little confusing.

To #3,
Why is it questionable to use moly in a #1?

I haven't shot this gun yet. It's brand new. I just mounted a scope on it last Saturday, and I'm waiting for the weather to cooperate before heading to the range. I live in Ohio, kind of humid in the summer, but nothing too extreme.

I thought that by using moly coated bullets I could possibly extend the life of my barrel. I didn't realize there was any down side to using them.
I have already bought 2 boxes of Honady Varmint Express in 40 gr. 4150 f.p.s. WOW!

Thanks, for any additional help.
 
Supposedly, the molybdenum disulfide traps moisture between itself and the barrel metal, inviting corrosion, or even liberates some sulfur out of the disulfide component to creates sulfuric acid, to eat away the barrel metal.

There's also the theory that the two dissimilar metals create a battery effect, with electrolysis happening to the detriment of the barrel steel. Never mind the fact that lead or copper fouling would create a much more viable battery.

Using moly doesn't preclude a person from cleaning the barrel, it just requires less cleaning compared to naked bullets. Here's an excellent technique for cleaning after shooting moly:

I sure do like my rifles, and I sure don't shoot any non-moly bullets through any of them. If there are problems with moly, it's news to me and my rifles, as I still get the same accuracy, after shooting moly for a couple of years. I haven't noticed any problems with my rifles' bores, but then, I don't own a borescope, so I don't have the capacity to look for microscopic changes.

I did hook one of my barrels up to a voltmeter, and I couldn't detect any voltage at all. I'm going to connect my VS barrel to a trickle charger and see if I can work up a charge. :)
 
Walter, I think you may have looked for voltage in the wrong place.

You should hook up the voltmeter's leads to the folks getting all lit up about how bad moly is for one's rifle. Might be enough juice there to at least run my Outer's Foul Out II.
