Hello I am in the market for a rifle. I like the Kel-TecSu16B, It folds in half and loads AR-15 mags. I think the AR-15 is a great rifle but want something different. My main purpose for this rifle would be varmint/ predator control. Questions: Would a .223 stop a Coyote quickly or would it just wound/maim the thing and make a mess? Is a .223 overkill on say a squirrel/ gopher? I like the look and length of carbines but what do you, the more experienced with rifles, recommend for an animal the size of a coyote?
