300 fireball for Coyote
 

I am going to build a 300 fireball for 2 reasons. One is for the man stopping ability and not to mention that the high cap mag issue is a great plus. 2nd is for the use on Coyote. I live in the mountains so a lot of my shots are going to be limited to 50 to 150 yards.
My question is this
I have about 300 bullets in 220grn hornady round nose. I know some of you have used this bullet and I would like to know what you think if this heavy bullet on a coyote. I know it is over kill but I want to use and practice with the ammo I may have to defend my familys lives.
