Varmint/rat problems/ .22 funtime

The little rats running along cables and in trees are "roof rats", which I understand are a native species. They live in the fanciest neighborhoods in Sac. You might damage an expensive cable if shooting at them on lines. I don't think shooting will do much since they can out-breed your bullets. If a food source, they exist. You should see the monster Norway rats that live in rock jetties on the FL coast. They might survive on just what the ocean washes up. I knew kids who shot at them w/ 22's, but not smart unless you can dodge ricochets. I have a 22 magnum w/ scope that is amazingly accurate. The bullet travels much faster than a 22 LR, but 22 WMR cartridges are 4x the price and hard to find.
