I agree with jh45gun about the SSS ammo. Not many rifles handle it well, but surprisingly....I also have an old Marlin-glenfield like s.summer does and it likes them,however........in my opinion....they are a novelty at best, but fun to play with. If I want something 'neighbor freindly' but still has some power, I use the Remington Subsonic ammo in the green boxes. It dosent have the 'crack' like high velocity ammo, but still arrives with some 'authority'.....and within 50 yrds it is still close enough to the same zero as standard ammo.
For really quiet stuff, I like the CB Longs. Regular CB's ar also quiet and they are easier to find than the CB Longs, but I have compared the two and the CB shorts are really crappy for accuracy. These are good for squirrels and rodents and for popping pests in the butt to get them away from the chickens, however....I am NOT sugesting that they will kill a yote. They ARE a lot of fun though, and Aquila also makes something similar.
