Too many to pick just one as "best"..................lots of good bullets today.
Choose what you like or can get today. Some of my fav's:
140 Partition
139 Hornady IB
139 Hornady BTSP
140 AB
120 NBT
120 TSX/TTSX
140 NBT
Any of the Sierra's for smaller deer; the above for bigger deer, elk & moose.
JMHO, YMMV
