Cleaning the Cetme L Chamber with a Boosteady Chamber Brush

The Cetme L has never run right, always jamming with failures to extract. Lately, I had a case break in the chamber. Someone gave me a good hint on how to remove it with a drywall anchor. You can check out that video at: https://rumble.com/v667cua-removing-a-broken-case-from-a-cetme-l-chamber.html

I thought it would be a good idea to scrub the chamber so I picked up a Boosteady Phosphor Chamber brush. It was about $11 from Amazon, not a sponsor.
