The 2nd day of gun season in N.Y.'s Southern Zone I dropped an 8 pt. buck using my Tikka .243 and the 85gr. Sierra HP loaded with 37gr. of IMR-4064. It was a broadside shot through the lungs. All he did was turn around, take 3or 4 steps & go down. For years I used a 30/06 and after similar shots the deer would run 30 to 60 yards before dropping. I am sold on this bullet!!!
