So I just got a 20practical (223 necked down to 20) barrel for my ar. My twist is 1-10 and I am wanting to go with heavier bullets. I will be calling coyotes out onto frozen lakes and would like to stretch out my shots as far as I can still hit with a headshot. I’m shooting for fur so ideally I want the bullet to loose all its energy inside. Any pet loads and bullets out there?
