A lot of semi autos have a hard time with that. I don't recommend it simply because if you'll shoot that, and then shoot a standard CCI, it's likely you won't hear much of a difference supressed. They are both subsonic rounds.
The only way to reliably run the Quiet in a 10/22 is to use a...
Define subsonic ammo. Are you running something like standard velocity CCI, or are you trying to run something like CCI Quiet in it?
If you're running something comparable to standard CCI I'm surprised it isn't cycling. What I'd recommend is going to a progressive spring kit, assuming you...
I'm a 10/22 lover. The bolt action ultimately will be quieter, and allow you to reliably fire 700+ FPS ammo. However, I'm not willing to trade the semi auto 10/22 for a single shot bolt gun...the decibel difference is just not worth it in my opinion. Standard velocity ammo is still subsonic...
Sounds good. I actually don't mind the weight as it is going on a 16" barrel which will hopefully balance out the weapon a little bit. How'd you manage to only pay $400?
