tumbled primed cases?

[fields]

I tumbled primed cases that were leftover from a reloading session three years ago. I cannot see any walnut stuck in front of the primers. Should the old primers be tossed, and have new primers inserted?

I would just load them and shoot them. Believe me if there was any walnut media in front of the flash holes it will move aside real quick when the primer detonates.

I tumble primed brass all the time with walnut. Never an issue.

I've done it several times. No issues when fine grade media was used.

Please excuse my ignorance, I'm new to reloading, but what is the value of tumbling primed brass? Why not tumble before prime?

Personally I wouldn't do that, and if I did, I'd look real hard at each flash hole to make sure all the media was out.

I don't know what happens if you have corn cob mixed in with your powder, but I don't see any reason to find out.

Give the cases a few little mouth down taps , this will dislodge anything you can't see and load them , should be just fine.

I would have loaded them up then tumbled them myself, or just shot them "ugly".

accident That is why I was worried.

I've been tumbling primed cases for thirty-five years. A speck of corn cob or walnut in the flash hole is a non-issue. The flash of the primer will remove it. As to finding out what corn cob will do in a fired case, people where loading cream of wheat and powder in cases to fire-form brass before I was born. It just ain't no thing.

Welcome.

You pose a good question. Note that in the original post fields said that the cases had been primed about three years ago and not used. While the reason for tumbling is not stated, it is likely that in the intervening years the cases had tarnished significantly and they were being tumbled to restore their appearance. They have have also been from a caliber that uses a bottleneck case and has to be lubricated before being re-sized and some people tumble to remove the lubricant.

Thanks for clearing that up for me hdwhit!
