Ok so just got word me and my dad might be able to do some coyote hunting here soon. I wanted to take the trusty AR out.. now will the regular USMC or WOLF ammo work or what do I need to use? I have never been coyote hunting and was wondering what is effective to down one with. Also If I only have a 30 round mag will I need to get a 10 rounder, or is there no limitation for yote??
