Military ammo is shipped by truck, plane, boat, helicopter, rail cars, jeeps, mules and humped by soldiers. Some probably hang around for years in all sorts of environments; hot, cold, dry wet and often a combination of all 4 before they reach the soldier's gun. An hour or twoin a vibrator cleaner is so mild as compared, it's like rocking a baby.Still not going to do it. Tumble on
, your choice. And if it’s in the net, must be true. You can’t equate powder jostled around in shipment to powder moving around inside a loaded shell casings in a vibrating machine.
And of course nobodies forgotten a machine and left it on overnight.
I normally stay away from this subject as I've been seeing it since I joined my first reloading forum in 2006 and both sides "discuss" their theories quite well but there has never been a consensus reached. If one wants to tumble their loaded handloads, fine, there isn't a lot of facts to say "don't". If one chooses to not tumble their loaded handloads, fine, there are plenty of opinions as to why it may be considered "dangerous", In other words; if you wanna, go for it. If you don't wanna, don't! But I got sucked in again.
