I shoot a Remington 7mm Mag. I shoot core lokt 150 grain bullets through it and i have never shot a deer with that thing that i havn't found. (Knock on wood) I have had my rifle for about 7 or 8 yrs now and have had plenty of people say that it is too big for NC deer but i disagree. The right grain bullets and you could shoot anything that you want with a 7mm mag.
