I have my rifle sighted at 25 yds with Win. subs. That puts them also right in there at 50-60yds.
Squirrels, Maggies are easy as usually they were around 25yds......pulled in by the bird feeders.

What's really brilliant with maggies is the 'wake' they have when one is shot. Just have to wait a few minutes and they're all around cackling...so shoot some more. I often end up with 6 or 7 on the ground before they clear off until later when I shoot another...then 'go' again!

Thing is, with the ability to nail them easily at 50-60yds without re-sighting, I can also knock over a crow or pigeon that land in the field too.

Cats I would dearly love to deal with the same way, but it is illegal in the UK to shoot them. So, no can do. Pity, but $h1t happens.
