CCI quiet is considerably more quiet out of a suppressed rifle, but is one of the least accurate rounds I’ve shot. It’s ok for showing people how quiet a suppressed 22 can be, but good luck actually hitting anything.
Not my experience at all. Just have to sight the rifle for that round. It's not meant for 100 yard matches. It's a plinker round and I can easily hit a 6 inch plate at 50 yards. YMMV
