I use a 177 Hw50 and keep all my shots inside of 40 yards. It's a great little gun. Light, agile, points and shoulders well. I also have a 20 caliber R9 and R1, 177 Hw95, 97, and 2 30s. IMO the R1 and 97 are way too heavy for me to lug around in the field. My R9 & Hw95 are essentially the same gun in 20 and 177. Those can be nice squirrel guns too. At roughly 16 & 15 fpe respectively they have a little more power than the 12 fpe Hw50.
Somehow I always grab the Hw50 because it's lighter, handles great and has sufficient power for the distances I'm comfortable shooting. Fwiw, I had a nice Hw50 in 22 but I kept the 177 because holdover is easier for me to calculate. As pointed out there's a million threads on this out there with a million preferences and suggestions. This is just what I like and why. YMMV
