brass cleaning

Hi, New here and to reloading. Curious about tumbling brass. I keep reading that you clean brass before removing the primer. My question is, Is it ok to remove primers first and then tumble? Thinking it would be better that way and clean primer pocket as well. Or could it damage the primer pocket?

Thanks

RE: brass cleaning

I normally leave the old primer in when I dry tumble. If you remove it, the media has a tendency to lodge in the flash hole and you have to push it out with a pin or some other narrow tool. I do remove the primer for wet tumbling and SS media. This cleans the pockets oh so nice, and with .047 pins, its hard for 2 to get in the same hole and get stuck. Wet tumbling gives you a cleaner case, but the batches are much smaller so in the long run, it takes longer for large quantities. In addition, you need a sink where you won't lose pins, but more importantly won't upset the missus. Another drawback is the case is "too clean" and the powder funnel may stick without the small residue to act as a lubricant. I pretty much just use the wet method for severely tarnished cases anymore.

I hope this answers your question,

RE: brass cleaning

Hello, I have not identified any damage to primer pockets as a result of tumbling them with the primers removed but I would say that if you tumble your brass with the primers removed I would recommend paying extra attention to media pieces getting stuck in the primer pocket, I see this and watch for it and it happens more often as the media gets beaten into smaller pieces. Just my thoughts, same as the previous; so I guess I agree then. J.

There is no reason to clean primer pockets any longer. Primer residue is non-corrosive now, and current primers won't deposit enough residue to prevent proper seating.

RE: brass cleaning

You'll get more dirt in your decapping dies if you don't clean first, But yes you can.
I wet tumble.
For rifle, I clean first,lube,size,trim, chamfer, deburr, then clean agian so to wash lube off, and ready for loading
For pistol, I clean, They're ready to load.I don't clean primer pockets on the pistol. The wet tumbling does a great job, both inside and out. Lots of video's on you tube. Every one has their own way. You'll find yours.

Good luck and happy loading

RE: brass cleaning

I deprime first because I wet tumble. With the primer out, the brass dries much faster. Getting the primer pocket clean is a side benefit.

I have never heard of a primer pocket getting damaged from tumbling. I also have removed the primer before dry tumbling, but only if you have fine media. The course stuff will get caught in the flash hole.
