    Has anybody ever put loaded ammo in a tumbler to clean it?
    I would not think this to be very smart, but then i'm not to smart anyway. I've been thinking about trying it.
    Guess i could decap it all then polish it. Then reload it.
    What do you guys think?

    I have accidently done it, would not recomend it at all, feeling very lucky to not have one go off yet. There is story's of ammo going off when transported in cloth bag and set down to hard. So could very well happen in tumbler. If you do it what hospital do I send flowers to?

    Don't send flowers send food. Hospital food is the worlds worse.

    I have not HAD to do this as I clean cases first. However I know pistol shooters that do this with ALL their reloads Thousands a year and never had a problem.

    This has been hotly debated here before.

    Many major manufacturers do this as a final step to make their product look good.

    I've done it on occasion. Never an issue.

    There are 2 supposed concerns. 1 is that the primer will go off. I don't see that happening. Primers need to be struck with some force to go off. The more likely concern is that the tumbling action will break down powder kernels and alter burn rate. I'd say that's more possible, but I've never seen it (and shot over a chrono vs. untumbled to verify). I'd not have issue with doing so in general, but wouldn't overdue it for hours.

    The counterargument to the broken-down powder theory is that ammo can be transported in vehicles for years and never have a problem, despite all the vibration.

    BTW, as a general observation: If the question begins with "Has anybody ever...?" the safe bet answer is "Yes."

    I tumble every single round I have ever loaded.
    So does every major ammo mfgr.

    There have been many studies and there is no degradation of powder as some interwebz "experts" state.

    Please quit spreading this falsehood.

    I think with some planing you can avoid tumbling your loaded ammo.

    A vibrating type cleaner would certainly be safer then a rotating tumbler, especially with pointed bullets. It still sounds dangerous.
    Don't believe I'd risk it - just my two cents.
    Good luck.

    Yes I have and would do so again.

    Just keep the tumble time short.

    yep, keep the time short. The right amount of time while vibrating will erode the coatings on the powder that control burn rate.

    Ammo in a truck for years is not the same as ammo Vibrated at a frequency for some period of time.

    I personaly don't do it, I clean my brass before loading and wear latex gloves when loading, therefore my loaded rounds are as shiny as the tumbled brass.

    Not correct
    I got to be involved in some studies at the Remington plant in Lonoke in my younger days.
    After 2 WEEKS in the tumblers, there was ZERO change in the powder or ammo

    Please quit spreading these rumors unless you have some data.
    And there isn't any

    I have no data from my own research, only what I have heard in reloading conversations in several areas over the years. some benchrest guys tried it and said they saw a difference in accuracy.

    post your data please.

    I agree with JustC - no traceable finger prints on my unpoliced brass either - just kidding....
    I reload new brass in this order:
    Full length resize
    Tumble clean
    Trim to lenghth & chamfer mouth
    Uniform flash hole
    Uniform primer pocket
    Prime, charge and seat bullet - with gloves
    Wipe with soft cloth and store.
    This method always produces optimum results in my firearms.
    Always looks better then factory new.
    If I missed anything please reply.

    Does anyone have load data on the 357 Max using Herco

    This topic was discussed on ASK THE EXPERTS forum last May under the heading CLEANING OLD AMMO. Manufacturers can tumble loaded ammo under controlled conditions as they can test the results safely, something not possible by hobbyists, who would have no idea of what might not be safe. I inquired of Hornady Tech and Federal Premium as to their advice. The upshot: NEVER do this/not recommended. I suggest a check of the archived pages of the ASK THE EXPERTS forum dated 5/4/10 for the verbatim comments.

    I have done it once but for a very short period. It is not really recommended.

    I re-sized once before
    tumbling and will
    never do it again.
    Cleaning the brass
    is my first step in reloading.
    I once spent a bit of
    time with a toothpick clearing
    flash holes free of media.
    Ain't no fun
