What's with small primer 45"s?

the story is long and ugly. Police departments insisted in lead-free primers because of heavy use on indoor ranges, and the apparent inability to make the officers involved actually run a clean range.

The new compositions had a higher force, and primers backing out became a problem. The ammo companies tried to solve it by making the flash hole bigger, so there would be less back thrust.

the long-term solution, for some, was to use small pistol primers, and they also found it helped make loading more efficient and less costly. (when you load by the million-round production lot, even a small cost change matters.)

So, save them up, they work just fine, and you can always trade them, or hold them in reserve for when you have small but not large pistol primers.
