Hi, i just got done building a 7mm rem mag hunting rifle. I killed a deer with a 150 grain nosler ballistic tip, i got him in the head (scope must have been bumped) and it removed a forth of his head. it made an antler fly about 20 yards, i couldn't find it for like an hour. I am afraid that a 140 grain nosler ballistic tip (i switched to 140) will remove a forth of the coyote too. I only have a 7mm rem mag, a 243 win, and a 257 roberts. the roberts is WAY to heavy to pack around and my father is using the 243. I'm not afraid of only taking head-shots with say an fmj if nessecary. what is the most fur friendly round you have found. Is a higher sectional density bullet better on fur? Because i know where to get really high ballistic coefficient and really high sectional density bullets. i dont want to have football sized holes in the side of them... thanks for any replies. Happy Holidays and if your driving, be safe.
