7mm mag is a great caliber for just about everything, but IMHO the Core-Lokt bullets are crap, in my experiences (plural) they are very inconsistant weather they open up and explode or pencil thru and you start a hard tracking adventure? I went with 175 grain NP's and have been happy ever since. I didn't start out with the 175's, the 160's didn't group that well, and so after alot of different bullets, weights, the 175 NP's gave me -3/4 inch groups @ 100 yds consistantly. Good luck!
