I used a Glock 31 (4.5" barrel) to fire 7 rounds of RBCD 60 grain ammo. It was semi bright outdoors so I couldn't test the flash very well. It appeared to be about 10" long and 5" wide. And the flame was a kind of orange-white. I'm guessing the flash would get more intense with shorter barrels.
Accuracy was good.
Felt recoil was similar to typical factory ammo, and probably even a little lighter. In fact, the Power Factor was a mellow 133.
CED Chrono results:
2214 High Velocity
2178 Low Velocity
36 Spread
2198 Average Velocity
17 Standard Deviation
My Glock could not match the advertised speed of 2410 fps. Maybe they used a 6" barrel. But at 2214 fps, it was just a little shy of twice the speed of sound
You can't use the thumb pressure test with this ammo since the lead tip is very soft and will be flattened. But I did cycle a round through my pistol 5 times and measured for bullet setback. There was none! In fact, there was reverse bullet setback as you will see with these figures:
1.1365 Original Length OAL
1.138 1st slide cycle
1.1405 2nd slide cycle
1.1415 3rd slide cycle
1.1415 4th slide cycle
1.142 5th slide cycle
The OAL seemed to even out after the 5th slide cycle.
The fired brass looked normal with no bulging, etc.
I would have liked to see some kind of manufacuring lot number or date on the package, as a reference point.
Overall, I liked shooting this round a lot.
This may be an excellent round for close quarters. RBCD ammo produces very high velocities, high energy, instant energy transfer into the target, bullet fragmentation, and shallow penetration.
