Moly coated 22-250 bullets ?????

I just purchased a used 22-250 rifle.It has seen moly hornady bullets only.Should I continue with the same? Is barrel cleaning more complicated? How often should the barrel be cleaned? Will accuracy be affected after cleaning more than usual? Is this moly idea a good idea at all? I'm new at this,be nice!

    I heard the pro's and con's of using molly and decided to try it for myself ... I bought a Molly kit from Midway and I've been using it myself for about 5 years for everything with a copper jacket.

    I like it, it seems like I get much less copper fouling so barrels clean faster and easier ... after I clean a barrel I run a patch coated with molly powder down the barrel to pre coat it and shorten the number of "stabilizing" shots needed to re-coat the lands and grooves.

    *EDIT*
    Before I started using molly, accuracy started to drop off noticably after 100 rounds or so, indicating the barrel needed cleaning ... with molly, this "drop off" doesn't occour until about 400 rounds ...

    If you really desire something, you'll find a way ?

    I need to try this stuff. Since it's slicker than two greased eels skrumpin' in a bucket of snot, does it prolong barrel life?

    Been using molly in three of my rifles. Tighter groups.Clean with three wet patches of kroil.Follow with dry patches.No need for brush yet.

    You would not have to keep using moly bullets, just scrub it good and start using "non" moly bullets and it will be ok. Your rile could possibly shoot better with out the moly bullets, try both and see.

    I have been shooting moly bullets in my 22-250's for about 3 years now and I don't see any difference in accuracy but a hugh difference in how quickly the barrel cleans up. Can get a little for speed with the same pressure too.

    well, I might as well start it. I tried it as well, and threw the rest of the box away. They grouped up great in my Sendero 7mm mag and my 222, that is, for about 6 rounds. After that, they started to open up. I pulled the bolts and looked into the rifling, and saw little balls of moly forming. Like I said, they grouped well for the first 5-7 rounds, but then opened up to about 3/4-1". If I am getting 1/2" with federal premiums, and then 1/2" with hornady moly coat,that's a draw, but when they start to grow the group after 5-7 rounds, I will stick with copper. Try it and see what your rifle likes. Me,........I don't really care about clean-up time. I would never run more than 20 rounds through a rifle without cleaning, other than a semi-auto battle gun.

    JustC,
    Have you reduced the size of your expander ball for the moly bullets?

    coyote-man, mine were two different premium brands of factory ammo. But, if I havn't been gone too long for you to check this thread,..explain the reducing expander ball thing to me in case I reload some moly rounds to give them another try. I have not heard of that.

    JustC,
    By reducing the "expander ball" 1 thousands this will of course give it a tigher fit. The moly bullets are slick, so this should be done to insure a better grip on the bullets. I've done this to all my die's that I use for the moly bullets.

    So,...are you saying that the bullets group or perform better if I reduce the expander size? I will try anything that improves performance. Does this have something to do with reducing the moly balls forming in my rifling?

    JustC.I had to do a lot of work with JB's bore paste on my sendero to stop the molly balls. It paid off.

    JustC - Are you using the pre-coated molly bullets or a spray on molly? I've never had a problem with "molly balls" but I use the molly powder from Midway and a tumbler to apply molly to my bullets.

    As varmit hunter said, it does help the neck to be tighter on the bullet but I just use a crimp die to get that extra milli-second of powder burn in the case ... haven't tried reducing the expander ball size, never thought of that! Exactly how do you do it? ... Real fine sandpaper (600 or finer grit) with the de-capping rod/expander ball in a drill? What is your secret?

    kimberkid, If memory serves, (not something to bet on), I think one box was hornady and the other box was winchester. they were in a 7mm mag sendero. I have never tried the moly applications because of my experience with the factory bullets. I have thought about re-trying some, but I havn't taken the leap yet. I know they are supposed to help the barrel, but how much? I just hate to have to clean the barrel like that again. What is the secret to this stuff, it just didn't work at all for me. Like I said, it grouped well for 5-7 rounds, then the group would start to grow by bullet width each shot after. I can get one ragged hole with federal premium 150gr BT. The moly just didn't seem to hold it's groups as long. Did I miss something?

    VarmintHunter, what did you have to do to get your barrel to like the moly or stop forming the balls?
