I have a Ruger Mark 2 with the long barrel, and 2 Taurus Tracker revolvers, in .22 LR, and .22 Magnum.
I use the Tracker .22 LR the most with CCI short hollow points.
Why .22 hollow points.
The shorts are quieter, and the hollow points kill the squirrels fast.
Just remember you get what you pay for.
Heritage Rough Rider .22 is a cheap made gun, if that is what you want go right ahead, but get the longest barrel you can find.
Short barrels are not accurate, longer barrels hit better at longer distances.


Just my 2 cents.
