I could live with a 7mag and a 30-06 and be happy.I think the 7mag is a little flatter shooting and the lighter weight bullets in the 7mag carry a higher BC than the lighter 30cal bullets.I think they become very similar cartridges with the 7mag using 160 and 175gr bullets and the 30-06 using165 and 180gr bullets.The advantage the 30-06 is,you have bullets over 200grs and it can still push them at a fairly high velocity.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
