Reloading PRVI brass, a primer pocket issue

While setting up to reload some 7.5x55 Swiss brass today, I noticed
an issue that needed attention.

The primers were quite difficult to seat, and more than difficult to get started.
It's not that the previous primers were crimped in, but the primer pockets
had no bevel at all to the hole. This made starting the new primers a bit
trying, and certainly time consuming.

Not to be beaten up by a lousy primer pocket, I reached into my bag of tricks.
Actually, I reached into a box marked "Assorted case prep tools" and here
is what I came up with:

This is a Lyman primer pocket reamer. Unlike my others, this one specifically takes off crimps and nicely rounds the corner on the pocket.

The fluted cutter is sharp and well shaped to do it's job. Only a few twists are required to ream the pocket to SAMMI dimensions.

The results, priming operation time was cut in half and the primer fit
was very consistent case to case.

This might be something to consider if you are trying to reload the PRVI brass.

With all the unusual European calibers being so popular in Mil-Surp shooting and collecting these days, the availability of ammunition can be a problem.
Hand loaders have no such problem, as long as components are available.
Importers are now bringing in strong lines of Igman and PRVI ammunition at good prices. In most instances the cases are brass and boxer primed, a great thing for hand loaders.

Occasionally we must adapt to small issues as we makes the brass work for us, and adaptability is key.

Remember, it's only technology! Never give up!

I've spent a lot of time here in the last week or so. I appreciate the time and effort that you spend in sharing your knowledge. I enjoy your writing style. It flows so well and is easy to read. I'm learning a few things too.

I usually use a Wilson case mouth deburring tool to deal with primer crimps and primer pockets such as the ones that you mention. A 45 degree counter sink works well too. Just chuck them in a drill and lightly touch them to the primer pocket. I'm getting old and doing things by hand is not as much fun as it used to be.

Best Regards
