To do so could result in cartridge detonation causing serious personal injury. The opportunity for a pointed bullet to obtain the velocity and force required to detonate a primer and ignite the round just isn't there. I agree that it's always good to err on the side of safety, but this just doesn't pose a risk at all. I too have been doing it for years to clean the lube of my finished rounds without a single issue.
I would say that if it makes you feel uncomfortable, don't do it.

If anyone is still that worried about it, maybe reloading is not the best hobby for you. Quoted: In the end I wouldn't want to see anyone get hurt. Aloha, Mark. I don't do it but see no reason not to do it. Of all the things that could go wrong during reloading, a quick final tumble causing a problem is waaaaaaaay too far down the list to cause worry.
It is perfectly safe. Definitely an old wives tale that tumbling loaded ammo is bad Aloha, Mark PS Tumble away! Well since all factory ammo is tumbled before it's packaged and sent out, I'm willing to bet it's not a bad thing to do for at least a short amount of time.
If tumbling loaded ammo were universally bad, we'd be hearing a LOT more reports of problems given the number of people who do it. Now, it's up to the individual end user to make the decision. Yes, there have been a very few documented cases of problems which MAY have been related to tumbling ammunition. But until I see conclusive evidence based on testing that shows the circumstances and mechanisms, those cases still exist in the realm of speculation and are far outweighed by the amount of empirical evidence from people who do it routinely and don't have any problems.
The counter argument can be made that it's not the odds of failure, but the consequences, and that certainly is a valid concern. I have done it and had no problems. I would not worry about the powder, breaking down,, I would worry about the Primer compound, that Might, break up,, Like I said I had no problems, after tumbling long enough to get the lube off, them. I have started to Wet tumble brass with the stainless steel media. That works well, and cleans up brass that corn cob, would never clean up.
Anything could happen,,, but I have not heard of that story,,. How do you think all the ammo in 20rd boxes looks so pretty? I don't know if it works or doesn't and anyway it's not for me to defend his posting.
The purpose of my linking the article, was for those that would say….. It was confirmed that the powder was in fact N and that the weight of the powder was correct.
Nothing wrong with his scale. However, most of the powder was broken down to much smaller grains than the original N Smaller grains, higher density, higher burning area, higher burning rate. Primer ignition material requires a high speed impact to ignite.. I don't tumble mine, but I have accidently had rounds in my brass from range sweep ups.. AeroE, Personally, I found your post to be "insulting. So, as I begin another self imposed hiatus, please give me equal time to respond to your latest posting by saying Some might agree with your assessment and some might not.
I vehemently disagree with your premise. Geoff Beneze performed a loaded round tumbling test for various intervals, the shortest being one hour, complete with magnified pictures, over 10 years ago. The vibratory tumbled powder was virtually indistinguishable from the non-tumbled powder.
Furthermore, when you consider that, say, all Remington ammo is trucked from their single distribution warehouse to points all over the nation, and also consider that road travel imparts vibrations to the trucked ammo for hours on end, it jsut plain does not make sense. Others have done simple experiments and concluded that they can not see visible signs of powder changes after tumbling loaded ammo and then pulling apart the rounds.
See, e. Moreover, AccurateShooter. The rifle was a highpower target rifle. The ammo was. The subsequent investigation concluded that the rifle blew up because the shooter had tumbled the ammo. The unfired, but tumbled, ammo was pulled apart and it was found that the propellent had been turned dust leading to a conclusion that the dust detonated instead of burned.
I do not know for how long the ammo was tumbled. Why is a safety suggestion a hard thing to understand? It is the policy of Hodgdon Powder Co. Vibration for even short periods of time may degrade propellants or change their burn characteristics. Vibrating propellants may cause coatings to wear off and edges or ends to erode. There is an ongoing debate amongst loaders if this is recommended by powder manufactures. Thank you for your time Dave holey. One well known major tumbler manufacturer reports that in years of testing as long as 20 years ago they could not verify any damage or even change to the gun powder or primers when tumbled in a quality vibratory tumbler.
Yet it is reported that your official website here that it does. I want to verify that this is your present position on this. That tumbling loaded ammunition in a vibratory tumbler can and does effect the gun powder in the brass case. Could you provide me with the details of your research supporting your position of polishing loaded ammunition or has that position changed? Is there scientific support for your published remarks? Jan 22, 2, Houston, TX. Old myth.
Tumble away, factory ammo is tumbled after its made. I have tumbled old pistol duty ammo that was turned in. The rounds that collect all the green stuff from sitting in officers mag pouches for no telling how long. Looked good and shot good. Dec 20, 0 Bay Area, CA. The powder are using has been transported thousands of miles being jiggled the whole way. An extra minutes is not going to make a difference.
Nov 16, 0 72 Ontario, Canada. Just use Lee Case Lube. Water soluable, wipe or leave on. I won't tumble loaded ammo on principle. Yes the manufacturers tumble their ammo, but most likely in a padded room away from personnel plus they are insured for this anyway, are you?
I was given several thousand rounds of linked 5. After delinking, there was some corrosion where the links rested on the brass. I tumbled all of this ammo for a min of 4 hrs. It shot just fine and I am here to tell you about it. Like I said, many ammunition manufacturers including black hills tumble their loaded ammo. For the record, I used a vibratory case cleaner and its not something I normally do. Just when surplus ammo needs a clean up. Jan 11, 7, 8, Florida.
Talking vibratory type cleaners only, any danger is from static. I would be amazed if it perforated the tumbler bowl. Jan 22, 3, 7 55 Dallas, Texas www. I have spoken with several of the powder manufactures about tumbling loaded ammo. Their advice was that tumbling ammo long enough to get any case lube off was not going to degrade the powder at all.
They said if you were to tumble it for several days it may effect it some. And factory ammo is also tumbled before packaging. I tumble my ammo after loading on a Dillon to get the case lube off. I only need about minutes worth of tumbling to do this. I have also tumbled some old 40 ammo to get the cases cleaned. However, I don't think I would tumble 50 cal ammo, but this would be common sense, I think.
They are too heavy and could impact the primer. But anything else smaller I would tumble. So, you are doing no damage to the powder inside the case when cleaning the case lube off.
Sep 15, 1 Gilbert, Arizona. Not tumbled ammo. Even if you could "degrade the powder deterrent coating" by tumbling, the few minutes required to removing the sizing lube would do nothing. Again, in review, most major ammunition manufacturers tumble live rounds, the military conducted a vibratory test and could not damage the powder, many people here and on arfcom tumble live rounds, and there hasn't been one anecdotal report of high pressures or damaged firearms as a result of tumbled ammo.
Does anyone have solid proof that tumbling live ammo does effect the powder? I have never seen it. We need to have this on Mythbusters. I wouldn't do it for expetended periods of time, but just to get a little lube off should be fine.
If the ammo is loaded with SMKs, though, I wouldn't tumble them. The little pieces of tumbler media can get into the hollow point, and are a pain to get out.
I don't know if that effects accuracy, but it can't help. Dec 23, 2, 1, ohio. Jan 31, 4, 40 70 Goldsboro, NC. There are no winners or losers here. If you think it is safe to tumble live ammo, then do it. If you think it is not, then don't. For myself, I have never found any good reason to tumble live ammo. If I had ammo that was corroded, I throw it away. Ammo is cheap, compared to say: bodily injury, my home, my rifle, et al.
If my brass needs cleaning, I place the fired case in my vibratory case cleaner with the fired primer in it.
I then lube and deprime. I myself have been tumbling the lube off of my Dillon lube loaded rounds for almost 10yrs I used to put cases into an old bullet box, pump some lube in there, shake the box, then load.
I now put them flat on an old cookie sheet, give it a couple of pumps, move them around on the sheet, then put them in a box and wait to put in the case feeder. I dont want the possibility of getting lube into the case mouth and mixing with the powder. It adds a step or two to the ammo making process, but I load all my ammo as match ammo, so I dont mind I tumble my bullets when my club lets me reload, but thats a different story.
Depending on the cartridge, you may notice that to a greater or lesser extent. A case that's easier to resize equals a press that's smoother and easier to operate - which means more consistent ammo, and higher volume I believe the concerns about tumbling loaded rounds is that the powder inside the case may suffer from mechanical damage, and so may burn at a different rate than originally constructed. This could be dangerous. However, it doesn't appear that 10 minutes in a tumbler makes any difference.
In fact, my compressed SuperComp loads have accidentally ridden around for a couple of hours, and I've had no issues I had the other half of the batch out. I shot them for groups, chronoed, checked everything I could and gosh darn it, there was no problem with the either batch of tumbled rounds Now I will not sit here and say that it couldnt, but in my limited experience it didnt, and hasnt caused any problems with my ammo for a long time I too have left rounds overnight, in the tumbler.
I'm not saying you should leave them that long, but long enough to remove lube is no big deal. I use One-Shot when I have it available, but used the Dillon pump spray lube once when it was all I had. Never tumbled or wiped off the loaded rounds after using the Dillon lube, and they caused no problems at all in my mags or my gun s.
I actually like the slight residue left from the lube. It makes the rounds feel a little slick when I roll them between my fingers. I've seen a lot of shooters deliberately lube their rounds just before loading their mags, but I don't have to. OneShot feels sticky to me - its slick under pressure, of course, but stuff seems to stick to it But, that's not the main reason, for me. The lube gets on my hands, and other junk sticks to that.
My hands get messy enough while shooting, I don't need to add to it!! I see your point. I did the same thing when I lived in Atlanta I use it on all of my pistol and loads, and a little bit goes a LONG way.. I've been tumbling loaded ammo for years with no issue.
