Priming Incident.

Buy a RCBS or Sinclair primer pocket cutter. This will get all your primer pocket to SAMI specs and get rid of any defect left from swaging. This tool is cheap and can be operated in a low RPM hand drill. After this treatment, the primers will all go in smoothly and save you a scare at a minimum and an injury at the worse end of the spectrum.

The primer pocket cutter is better than chamfering and swaging. It cut the pocket to SAMI spec in all dimension.

There is absolutely no need to force a primer in a pocket - use the right tool - do the job right. :?

The thing I worry about is repetition between cases. How do I ensure each primer pocket is the same with a rotary cutting tool if it doesn't have a stop?

Swaging may not be perfect, but on the 1050 at least it's a repeatable process.
 
Canuck223,

The Sinclair pocket cutter are made for benchrest shooters. They do have a stop - a step that bottom out on the case head.The tool head can be used on a hand drill than ran below 1100 RPM. This is a very effective tool. The only way to go to uniformize the pocket - diameter and deep.

The goal of the swaging is to remove the military crimp on brass case. It work but run the cutter after and you will see the difference.




Sorry for the quality of the photo- will post a better one tomorrow.

Janeau is right. I do not swage and use only new factory brass and I still Primer Pocket Uniform each primer pocket with the RCBS tool. It's excellent and fast in a cordless handdrill clamped to the bench and very fast. And you do it once the first time you load that case and its good for all the reloads. As a matter of fact, I use it to clean the primer pockets instead of the wire brush, its faster and makes a "perfect" pocket and keeps it that way. If a significant amount of primer residue cannot be cleaned out of the bottoom of the pocket, your primer pocket and therefore your case head has stretched somewhat and you are nearing the end of that case's safe life. Takes no extra time, really. I also highly recommend deburring both sides of the flash hole - you will be surprised how mush flashing can be left over after they punch the flash hole and this obstructs consistent flame travel ... but thats another topic
