    Anybody do this after reloading to remove case lube? Just read about somebody doing just that. I'm using a single-stage press and this would be easier than wiping each case with an old t-shirt right after resizing. Opinions?

    I do and have never had a problem in two years since I started. I seriously doubt that you would be able to hit the primer with significant enough force while tumbling. Flame away :D

    I don't. Then again I use "One Shot" aerosol lube. leaves enough residu to not get the case stuck, but not enough to gum up the works.

    I use to have some 9mm cast that were coverd with lube goo. I always tumbled them after loading to get the junk off. When I load 223 I also tumble them to get the case lube off as I load on a Dillon. I tumble in corn for only a few (15-20) minutes.

    Tumbling loaded rounds

    I have done so on occasions, as above never had a problem.

    I throw all my finished rounds in my CV-500 for about an hour. Gets rid of any lube left on the case or bullet. Occasionally some bullets have a little flash at the parting line, tumbling smooths this out.

    I use Dillon spray lube on my .223 cases when I load on my Dillon 550. So yup, I tumble no longer than an hour to get the lube off, sometimes less.

    :what: I don't put live rounds in my case vibrator! I have heard that it is possible for the powder inside the case to be affected. Something about the coating possibly being damaged and thus changing the burning characteristics of the powder.

    Tumbling is fine for loaded ammo. Powder is "tumbled" when it is made. THe "tumblers" they use are extremely fast and would make ours look like nothing. People have tumbled ammo for literally weeks to see if it affected anything and it never has. It will do nothing to loaded ammo. Factory ammo is tumbled anyway.

    I routinely tumble my 357sig rounds for 11 minutes once they are loaded to remove the lube. Why 11? I don't know it just seemed right. I only load aa9 in the 357sig and it never seems to be a problem.

    I'm new to reloading, but I have a couple of friends that tumble after loading to moly coat their ammo. I was/am planning to do the same.

    Factory ammo is tumbled.

    Then it's "shaken", via the shipping and handling on the semi-trucks, etc. No danger to the powder's burn rate being modified.

    If I'm making a big batch of FMJ ammo, I usually tumble the stuff for about a half hour in corncob media.

    Arub, are they moly-coating the entire loaded round? That sounds an awful lot like lubricating the entire cartridge, which is NOT a good thing. (Boltface thrust, etc):eek:

    Tumbling Live ammo

    Tumbling your live ammo may not be dangerous if done for a few set minutes exactly for each batch of competition ammo but the powder particles inside of the cases, particularly the violent action of vibrator type cleaners can abrade off the coating on powder particles which changes the burning rate and pressure and can change the POINT OF IMPACT OF YOUR carefully loaded match ammo. Now who wants that?

    Tumbling in corn cobs for 10 minutes exactly with a couple tablespoons of cheap paint thinner or kersone will do the job and match ammo should have every lot of components identical and every proceedure identical to always have the same point of impact with your sight picture for the life of that particular batch of ammo no matter when fired!!

    So there!!

    Understanding that you're new to reloading, but you're incorrect about what your friends are doing. I've moly'd thousands of bullets and I guarantee you that you don't moly 'em after they're loaded!

    Thanks for the 'save'. I checked with my friends and they moly coat the bullets before loading. I appreciate your 'heads up'.

    doesn't everybody?

    Several years ago I bought a small electric cement mixer just for tumbling cases . I use about four to five times the bulk of ammo in attrition milled cobs twenty minutes later it's ready to go .

    Moly coating poor method

    I have been a commercial reloader and the moly coating was invented for them as an excuse to not do the labor intensive sizing and lubing of bullets. Many of them now swage their bullets so they have the proper diameter before coating with moly. Home bullet casters have their bullets come out of the molds slightly "Out of Round" from the pulling of the mold halves before their bullets are completely hard. Home casters also use a variety of metals for bullets that can create different diameters when cooling depending on the antimony content and the size of the batch of lead. Moly dipping or spraying those bullets that are oversize and out of round needing sizeing to the proper diameter for your weapon creates a poor quality bullet for competition. Oversize bullets need increased pressure to move them and unless your bullets are sized they are not considered a proper quality bullet for anything but plinking. Most aerosol propellants and solvents are considered hazardous to your health and moly can be an excuse to not purchase a traditional sizer luber used by competitive shooters to make quality bullets for many decades

    Now how many of you readers spray or dip then size your bullets before loading? Or spray or dip them as they come from the mold then load??

    Also unless you make a large amount of an identical hardness batch of lead for casting and only make up your lead alloy from tire weights and other scrap lead in a 15 to 20 pound pot and the batches can be different compositions then the unsized bullets from each batch of lead can have different diameters??

    Something to think about if you want quality bullets to win anything in competition!!

    Damn it, I knew it wasn't me!

    All this time I figured it was just me. I knew I should have been a IDPA Master, instead of just an Expert, by now and all this time it's been those home cast, wheel weight, Lee 6 bullet mold bullets.

    And I figured that those nice tight groups at 25 yards would translate over to competition. Those bullets were just shining me on. Retribution will be fearsome and quick. I am going to kick them in the *** with some hot gas.

    I don't moly-coat cast or swaged bullets.

    But ALL of my jacketed bullets get the moly treatment. Even the Nosler Ballistic Tips.

    I moly jacketed rifle bullets only. Tried molying a batch of jhp's for .400 Cor-Bon, turned out to be a BIG mistake. Bullets are too slick for decent neck tension and setbacks are guaranteed!

    -Tumble with Walnut media
    -Lube and resize
    -Tumble with CornCob Media
    -Trim if necessary
    -Clean any remaining grit and/or corncob particles from primer pocket.
    -Load 'em up!

    I had heard about tumbling loaded rounds causing the powder coating to wear off or the powder breaking up into smaller pieces and affecting the burn rates. Near as I can telll, though, this is really only a problem with old powder and/or pulled surplus powders. I've never read anything about folks having trouble doing it when new(ish) powder was used. YMMV, as I've never actually tumbled a live round as the case-prep ritual above would indicate.
