Rat shoot with NiteSite Viper and .22LR

We have been having a problem recently with rats nicking the wheat that we put out for the pheasants. We have some rough weather forecast for the next few days with a big dump of snow, so I thought I would spend 20 minutes and ambush a few of the little buggers.
I am using my CZ452 in .22LR and my NiteSite Viper which is great for this sort of operation.
I must add that the clarity through the scope is much better than you can see on the footage, and that is the downside of the Rtek.
I got 5 altogether but quite a few left and will get back in a few days.
If you don't like killing rats then don't watch it, and please don't start saying "but a rats got to eat aswell"
Go watch a video about penguins in a zoo if you think like that, or get some housework done.
