....for whitetail deer, in factory ammo, I think the Remington Corelokt bullet is almost impossible to beat. When reloading my 6.5 Swedish mauser, I use the Horndady 140gr bullet.. it has worked flawlessly on two whitetails of very different body size...one very small "frail" forkhorn, and a large, big bodied prime 11 point. Both bullets impacted at about 150-160yds, and both exited after jellying the lung area....neither heart was hit, but both deer dropped on the spot, kicked once or twice, and expired. You can see why I like, and recommend the Hornady. I've had good luck with several different bullets of theirs.
