How did this post go from 22-250 vs. 223 to 50 cal? Did I miss the new thing of hunting squirrels with 50 cal? If thats the case guess my 300 win is not nearly enough for elk.... What do you guys recommend then??? I have some experience with the 120mm gun on M1A1 tanks.... Is that enough? What should I use for Bear, Nukes? And I don't even want to picture what will be recommended for cape Buffalo LMA0
