Help?

[Ugluk]

I think I know what you're referring to. The round rides up high and gets pinched by the breech with the nose on the extractor notch and the rim still in the mag?

When it happens to me I hold the gun in my left hand, thumb web high on the grip and the rest of the hand pulls the toggle back, leaving the other hand free to poke the round back down in the mag so it can be removed.

Muzzle in a safe direction!
