Saw one do this, but it was due to improperly reloaded ammunition (no crimp on a lead bullet; case mouth O.D. was .480+). What, specifically, was the cause of your observed malfunction in this regard.
And what is a Tactical Response class? Something local?
.
Cause: The gun
All ammo is factory, no reloads allowed in classes (For this reason)
Yep, that Tactical Response.
