So far I’ve put 250 rounds through her.
This has happened a few times.
Example here in the video.
Today at the range I shot 100 rounds and this happened about 4 times.
Reasons?

Using PMC Bronze .357 Mag 158gr. JSP

Tighten up the screw (and throw a bit of blue loctite on it) on the underside just forward of the lever. Same issue I had when I had my Henry Big Boy in .44. Should solve that problem for the most part hopefully for ya!
