Propellant damage from tumbling loaded rounds - an experiment.

another myth. I am sure that if tumbling after was an issue, then manufacturers wouldnt do it. Most major ammo manufacturers post load tumble to polish before packaging..

As far as I know Ganderite used to make amunition for a living. I am going with his answer.

Agreed. If anyone knows ammo it's Ganderite.
Like he says the graphite coating is intended to help dissipate static electricity. Graphite is also a dry film lubricant which further protects the powder kernels from abrasion.

I absolutely LOVE it when a CGN'er takes matters into his own hands and busts a myth. Thanks for taking the time to do it, and posting the results.

Yeah... I think it's great...

I mean, I've heard for years that tumbling loaded rounds for even a short period of time will cause the powder to break down. I always took it with a grain of salt because I'd never heard of anyone testing it.


Very cool.
