My favorites are:
1) Hornady .308 Interlock 165 grain
2) Remington .308 PSPCL 150 grain
These have accounted for the most kills at our camp over the last two decades in 30-06 and 308 WIN.
Before I retired it, my Rem 7600 Whelenizer had the camp record for most deer taken using Remington .358 200 grain SPCL.
