interesting read never knew that.

We take for granted the manufacture of so many products these days.
It's funny that a .22RF is such a hard cartridge to make, yet the .22RF short was one of the very first self-contained cartridges.

Ground glass? Now I know the source of the grit that is found in the action of rimfire semi auto rifles after a long day at the rifle range...

That grit is why many of us do not clean our .22 barrels very much. Dragging grit through the barrel is more erosive than shooting.

Interesting read. Thanks for sharing.

Thanks for posting. I knew there was ground glass in the priming compound but didn't know it was to facilitate ignition.

great post, the glass thing really explains A LOT!

My only problem with this theory is that with each shot the round is creating and dragging these particles down the barrel. I have seen a muzzle ruined from a cleaning rod, but how is a patch dragging down the barrel any more damaging than a bullet that keeps adding more abrasives with each shot. Those particals are going to imbed in the lead and drag between bullet and barrel all the way till the end.

This article makes it sound awful difficult to make these, yet they mass produced them 100 years ago. How could anything so hard to make be so cheap.

Yep.
