Things I liked:These blanks work great. My Track Starters' association bought a number of these recently and the are perfect for the job. The put out a sufficient amount of smoke for the finish line to see. The are definitely loud enough for the athletes to respond. There have not been any "clicks", that is, there have been no duds in the packs we have received. Things I would have changed:none What others should know:N/A
Things I liked:I order these shells for my Track Starters association. We start youth and high school track meets in our area. The shells produce a loud report and a good amount of visible smoke for timers and spectators to view.
No one has reported any problems whatsoever with the Umarex shells listed here. "No misfires, easy to load and easy to remove from the chamber" have been the comments I have heard.
The Walther shells that have been used as replacement shells in some of our orders have even more power, a loader report and a good amount of smoke. Things I would have changed:No changes on the Umarex blanks. The Walther blanks chamber just as easy as the Umarex, however, the crimped ends on the Walther blanks open up more upon use. this makes them more difficult to remove from the chamber. Occasionally, it requires an additional tool to push them out.
