Does anyone know whether polishing loaded rifle cartridges in a brass tumbler poses a danger and if it does pose a danger, is the danger accidental discharge or degradation of the gun powder. If you answer this question, please state the basis for your opinion or direct me to the literature where you found the information. Thanks

No, you should not tumble any type of loaded ammunition, per instructions on any tumbler you purchase. If you don't have the instructions you can log on to www.midwayusa.com, click on any tumbler they offer and bring up the instructions. Happy shooting!

The reason for not tumbling loaded ammunition is that the coating on every granule of powder will be worn off or damaged by all the tumbling. This coating is there to control powder burning rates. By wearing it off, the increased burn rate will cause a pressure peak that will probably damage the rifle.

There are lots of reasons not put live ammo in a tumbler. The 2 easiest ones that I can think of without having to cite anything are, the risk of impact to the primer, and heat of friction of the material could cause a round to cook off.
