I just got back from the range with my MP5-22. I ran 3 types of ammo tonight:
1. Federal 36-gr HP HV 550 round bulk from Walmart
2. CCI 40-gr standard velocity (1070 fps)
3. CCI 40-gr quiet (710 fps)
I loaded up 5 rounds of each going from loud to quiet. Federal being at the top of the mag, then the CCI SV, then the quiet. There is a distinct difference between them all, but the CCI quiet is not usable in the MP5-22. The standard velocity stuff being subsonic is noticably quieter the the Federal. I was expecting there to be little difference in the 2 types of CCI ammo, but the quiet sounds almost as quiet as suppressed .22. The only problem, I had to manually cycle the gun because I was getting a fail to eject every single time. I'm going to save the CCI quiet for the bolt action.
