Got a .223. It's overkill for crows, which is what I want the .17 for. Range of 200 yds or less, usually. The .17 is quieter and less chance of a ricochet as well. I live out in the country, but I do have neighbors. Sometimes a .22 LR is fine, but often it's not quite enough.
Crows are about the only thing I need it for, so I don't seem me spending the money for both--especially when there are so many longbows and recurves I want to own yet...and a few pistols.
