I currently have a model 12FV in .223 and I am looking to re-barrel it. I am wanting it to be a great varmint caliber for coyotes and the like out to 600 or so but would like to use it for whitetails if I want to as well. Not wanting to get too wild on wildcats because this will be my first build with a barrel change but I am really looking into just a McGowen 22-250. Thanks for the advice! Here are some pictures of the gun how it sits now.
