Terry,
As the bullets in the factory loads have improved, I have moved down in weight in my .308. The last Canadian whitetail (a 300# 10-point Sask deer) I shot with a 165 gr Trophy Bonded.
In Texas I would shoot the 150 gr Nosler Partition.
As noted above, the military bullets are not suitable for game, and most places don't allow their use either.
