TiteGroup is an extremely dense powder and very easy to double charge. It also burns very hot so the gun will get hot with fast shooting. It is also temperature sensitive so loads developed this winter will be hotter next summer. The most common sign of overpressure is flattened primers or primers which look like they have flowed back into the fring pin hole. With a Glock this shows up as a very pronounced raised box around the striker indentation.
