    Can some one please tell me if Moly coated bullets are good or bad? Berger sells moly coated bullets, yet i keep reading that moly can cause bad things to happen. Any help would be great..

    Moly Bullets

    You might try www.varmintal.com since there is a lot of good handloading information. There is a blurb about moly bullets on that site. Apparently the Moly coating can etch metal if it's not stainless steel but "Al" still likes them; you just have to clean your barrel compulsively after using them. You can apparently get more velocity out of moly bullets but I'm not intending to use the since I'm not convinced that the extra 200 to 300 fps is worth the cost and potential barrel damage if I can't clean it promptly.

    I bought some to try in a new M1-A I was trying to find the preferences of. I have never seen a centerfire rifle (or any rifle as far as that goes) behave like it did with them. I forget exactly how many I fired but there was absolutely no group. Several actually missed the target backing, which was about 3X3, at 100 yards. This was a brand new barrel with less than 50 rounds through it at the time. That may or may not have been a factor, I don't know, but I had some surplus military stuff and some Remington factory rounds I fired that same session which performed normally. I won't be trying any more.

    I think that some like moly and some don't.

    The list of advantages and disadvantages get scewed, depending on to which camp one belongs.


    1)
    a) Moly seems to be at an advantage with many shot at very high velocity.
    b) No moly seems to be at an advantage with few shots at low velocity.

    Even so, only half the bench rest shooters use moly, and that is many shots at high velocity.

    2) So the break point may be a question of personal preference:
    Do you like to fight Copper or molysulfide?

    3) There is a discipline requred to use moly , and my friends are not up to it, and do many silly things with the moly products.
    http://www.bergerbullets.com/faq.htm
    I like to use moly with virgin barrels, lyman bore creame burnished in the bore before the first moly bullet is fired.

    4)
    a) My understanding of benchrest shooters is that moly allows them to go ~15 shots instead of ~8 between barrel cleanings.
    b) My personal experience with .223 2,500 fps 60 gr and ground squirells is that I can go hundreds of rounds, and get no fouling at all.

    I have a friend that was seriously into PD shooting. He used moly in a .243 that he loaded to very hot levels.

    He told me that the barrels lasted a little longer and that fouling was a non issue.

    But the one thing to be aware of is that moly use is either/or. If you go that way you have to stay that way to get the most from it.

    With half of the bench rest competition people using it you could say using it is a toss up.

    I've never heard of anyone seeing any significant difference between MK and non-MK. You'll need to come up an extra 1/2 MoA with MK bullets because the velocity will be a bit lower. The rifle is easier to clean with MK and will return to zero more quickly after cleaning.

    Moly

    Moly or No Moly That is the question. Moly is a soft metal of sorts,firing moly coated bullets down the barrel of your favorite rifle or pistol will not etch the rifling of the gun, but what it does is build up tiny platelets in the grooves. So it needs to be cleaned as you would if you werent shooting Moly. I;ve shot both from a Sheilen barrel in 308 168gr with the same charge with not even a 25fps difference. So let you conscience be you guide. Have a Happy NewYear and safe shooting.

    They have yet to invented the super bullet. And Moly is, by no means, a super bullet.:scrutiny: I'd rather spend my money on Barnes solids and experiment with them. I believe that would be time better spent. 'Course I'm a hunter not a target shooter...:neener:

    Moly or No Moly is not as important as the barrel bore lapping at the factory.

    A Lothar Walther is so much better than an Addams and Bennet, that moly or no moly has only a second order effect.

    Last time I saw Walt, I didn't notice what he was shooting. I'll pay attention next time. I do know that moly doesn't "make" accuracy. It won't make an inaccurate barrel a hummer. I know one gentleman who shoots silver bullets, and he'll get some small groups, and the occasional yardage. I think it may be coming apart on him long-term tho...

    For a deer rifle, it doesn't matter.
