I used Win Power Points for many years when they were still being produced in Australia due to their great accuracy in my rimfires. I would sometimes find the bullets next to a sage rat as 1minute shows and it would be flat and about the size of a nickel or more.... these are hollow points. I've used just about everything but nothing seemed to equal the instant kinetic kill these would result in. For tree rats, just about anything works, as squirrels aren't particularly hard to kill and won't crawl into a hole in the ground to get away... as long as they are accurate in your rifle I would shoot what you brung and have a good day....
