I'm going to concur wth the others and say the 100 gr. CoreLokt if your gun likes them. My dad hunts whitetail exclusively with a Savage .243 and has for 20 plus years, no deer have walked away, and if they did, tracking woudn't be a problem.
I use the Corelokt 150 gr. in my 30.06 and I like the high shoulder shot, no tracking, and great penetration.
