There was gas cutting in the top strap above the forcing cone, but it tended to cut to a minimal depth then stop.

It really didn't cause much of a problem, but scared the hell out some owners.

But the truth of the matter is most cops back then (at least down here) couldn't afford to shoot enough Super Vel through their guns to worry about.
