Finally got around to doing some testing of my various 9mm reloads with the TC-73. Some good increase in speed with reloads using WSF (S&W 929) and Titegroup (CZ Shadow) when fired through the TC-73. Interesting the increase in speed with reloads using N320 were much lower. I even tried a 9mm Major load and got avg 1622 fps. With how solid the TC-73 is built, recoil is minimal.
Grouping ~1" at 17y, next would be taking it to the local outdoor range and try it at 50y, and maybe 100y. I think the limitations there would probably be the iron sights & my old eyes
9mm ICORE load and 9mm Duty Pistol load
I tried the N320 load with standard CCI small pistol primers, and one with small pistol magnum as the SD was a little bigger than when I load N320 & 124gr Campro for IPSC. No meaningful decrease in SD, but a noticeable increase in average speed. I think N320 may not be ideal for these light Duty Pistol loads, will just stick with Titegroup.
I didn't bring an Open gun for the 9mm major, but I think it's ~1400fps, so a healthy boost out of the TC-73 to 1622 fps
