Since I've been working on the 22 Reed Express I have been focusing on the performance and reliability of the system. While researching the 22 Reed Express and the 22 TCM, it seems people who have shot the TCM are more impressed by the muzzle flash than the package performance. Well, boys will be boys, as they say. Anyone who has loaded up hot loads with 296 and short barrels will get muzzle flash. I'm not complaining here, fireballs are fun, just an independent observation about an industry that usually is concerned about flash suppression.
Let me back up a step: When working on the 9mm DI set up, you can get them to work with the Tok gas system simply by reloading with a slower powder. If a factory had offered some slower powder in the 9mm, the DI system would have been a simple conversion. The IPSC shooters did this years ago to get as much gas as possible for their brake systems. It also would have produced muzzle flash in a pistol. But that has not happened yet.
Being the inquisitive guy that I am + the fireball fad of the TCM, I loaded up some 9mm with some slower powders to check performance. Using Quick Load, Lil Gun and H110 were too slow to get enough powder in the case but Herco could be loaded to the brim. It turned out 7gr would just overflow the case. Case capacity is listed as 13.3gr H20 (16.1 on the 22 RE). This gave me velocities right up to the 1400 fps range without going over max pressures of the 9mm. I also load up this same wgt load for the 22 RE but its just over pressured. There is a bit more to be had by using some other powders but we'll get to that later.
Ammo Guide lists over 480 loads for the 9mm. Bullets range from 90 grs @ 1500 fps w 457 ft-lb to 158 gr at 1020 fps w 378 ft-lb energy. And we all have been through the velocity vs wgt vs energy debate. Not having a 9mm until I built an AR, I did not have this first hand information so the bottom line of what I'm after here is (based on the TCM hyper velocity muzzle flash and having to buy another gun to get it) :
We need lighter bullets!
