Our Dept. of F&W has just announced the are going to do an aerial (helicopter) feral pig elimination at the end of this month in the desert marshes of Central Washington. Somehow I don't think that will work (LOL). Those marshes out in the flooded sand dunes behind Potholes Res. are choked with Russian olive thorn trees, tules, and sawgrass. Since I do a lot of fishing and coyote hunting in the desert and marshes just south of there, I may have to rethink what I have been shooting the last couple decades. My trusty 204 may be set aside for something with more "authority". I can just envision a 400+ yard shot at a pig across basalt coulee with a marsh in the middle.
I can see feral hogs doing well out there. Our winters are just too harsh west of the Cascades for hogs to do well. Feral hogs can handle a Russian winter but our incessant 33 degree rains are a different challenge.
