One bullet that fits "The Best" in my reloading book has been the .308 165 grain Hornady Interlock SP. Back in 2000, I was just getting started with reloading and the guys at shooters.com suggested it as a good place to start. I was contemplating a combination deer/boar hunt in the Texas Hill Country and I had two 30-06's that were going to be making the trip.
The Texas trip fell through, but I ended up buying a 200 acre farm the next fall. Those Hornadys were with me on that first Opener and the bullet has been part of every season since.
The starting load worked was so accurate in my Winchester Mod70, that I stopped there. Since then, I've used that bullet in several other rifles, including my favorite Opening Day deer rifle, a Savage 99 in 308 WIN.
My runner up is the .308 150 grain Remington PSPCL. My sons both have WIN Mod 70's in 30-06 and I load that bullet for their deer loads.
I'll put in two honorable mentions:
1) .358 200 grain REM SPCL in my 35 Whelen.
2) .257 117 grain Hornady SP Interlock in my 25-06
