.308 Win. is a great round and one I have used to years for deer. I did have a problem with it this year though. Gave it to my buddy to use for his hunt. He killed his 7 pt. nicely, but I was using Sierra Pro Hunter 150 gr. bullets. He didn't get a true-n-thru shot. The bullet hit a rib going in and shattered. It took out both lungs, but pieces went down into the ponch and made a mess. I will be looking for a new bullet for future hunts.
As an aside, I didn't over load this round. I used 47.5 grs of IMR4895 if I remember right. That is a mid range load in the Sierra reload book.
