I keep my performance equation very simple. For me, I'll take a super premium bullet that is somewhat heavy for caliber pushed as fast as I can handle. Penetration has never been a problem.

I've had a slightly different experience with the Nosler Accubonds. I've used the 110 grain in my .257 Weatherby and it penetrated the length of a Pronghorn from front to hip at 300 yards and retained 65% of its weight. I shot a wild boar with my .270 Wby using a 140 grain Accubond at 80 yards and it penetrated completely front to rear on a quartering angle. Another shot with the same .270 and same bullet at about 100 yards didn't penetrate all the way and the recovered bullet retained 60 % of it's weight. Similar experience at a 130 yard shot at a deer with a 180 grain Accubond out of the .300. So far, so good!!!
