I shoot 140 gr. accubonds in my 7mm rem mag. I'm not a fan of the heavy for caliber bullet theory, especially since there are so many good premium bullets on the market. 40 years ago the heavy bullet theory might have been true because you needed the weight and slower velocity to get the bullets of the day to hold together, but not any more. Loading a 160 gr bullet into a 7mm rem mag turns it into the equal of a 30-06, which is not what I'm looking for. I mainly use the 7mm mag for it's flat shooting abilities and don't want to give that up by handicapping it with a heavy bullet. There's no reason to use a 160 gr 7mm bullet on deer when the 140's will shoot through them from any direction. You likely won't find any difference in accuracy between a 140 and a 160 gr bullet, either is just as likely to be accurate.
