I ran out of my normal garden varmint fodder, CCI CBLongs, and bought a pack of Remington CBees. Supposed to be low noise. WRONG! Not quite as loud as high velocity Long Rifles but sure not quiet. They also don't shoot for beans nor feed at all well in my 10/22 when hand cycling the action.
After the CBees debacle I bought CCI subsonic long rifles. They are louder than CBLongs but not not as loud as the CBees. Also tried RWS subsonic low noise and those are a joke. Loudest of the supposedly quiet stuff and have enough snort to cycle the 10/22.
One shop usually has CBLongs but they were out. They are ordering more but it will be a few days before I have my hands on them.
I just put a new scope on the rifle, looks like I will have to zero it with what I can get right now and zero it again when I can get the stuff I really want.
