Either would do the trick. There are situations where I shoot for the shoulder but you are going to lose more meat with that shot. A shoulder shot does usually produce a shorter tracking job.

Some of the animals that I hunt require a shoulder shot due to the location of their vitals. For those critters a tough bonded bullet is a good choice.

A 140 bonded for the 7mm-08 and a 150 for the .30-06 and you are set for deer sized game and larger game also. With your cartridges you have plenty of energy. A heavier bullet is certainly not needed for deer.
