The rifle I used this year for deer was a Rem 700, SS, 30-06. In my readings, I found that the 168gr bullet was supposed to be the "optimum" bullet for 30 cal, due to its sectional density and ballistic coefficient. I use the win supreme bullets you mentioned and they performed very well. Two deer, one at 84 yards, and another at about 143. Each fell in their tracks after being hit low in the chest. I am very satisfied with the 168 gr and will use it in the furure. They are also very accurate in my rifle.
Good Hunting, Hal
