In my part of Maryland we have about 3 inches of snow on the ground. I felt bad for the birds and put a bunch of of bird seed around the deck and in several feeders. I have been seeing little rodent foot prints all around the seed so I made up several .17 Remington rounds using just .177 lead pellets and magnum small rifle primer. (no powder).
I was watching the birds eat when I saw it. A fat mouse running around eating. I went to the gun safe, got the contender, loaded one of the primer powered rounds. when I go back to the door the mouse was still eating and did not notice or care that i was 10 foot away in the door way. I took carefully aim and squeezes the trigger. the pellet struck him right behind the left front leg and went on trough and bounced around on the deck. the mouse dropped in its tracks and never knew what hit him.
This seams to be a very effective, quiet and cheep use for the 17 Remington
