RE: Best .308 cal hunting bullet
Not many people use it but I really like the 190 grain Hornady BTSP. I started shooting the 190 grain Hornady BTHP Match bullets for steel silhouettes many years ago and started using the BTSP version for hunting so I didn't have to readjust my scope. They were very effective. For deer, almost any good 150-180 grain bullets work well. You never go wrong with the Partition. Its a good insurance policy.
These days we are blessed with many very good bullets. I also like the Sierra 150 grain Pro-Hunter for deer.
