All around...180gr Speer Hot Core or 165 Speer Hot Core.
Both of these expand well, but retain their weight well, also. I have become a firm believer in bullets of sufficient weight to plow through the animal and break bones when necessary. :idea:
I feel any good bullet from 150 gr to 200 gr in a 30 caliber is good medicine for deer. I like heavier bullets for another reason...they don't ruin as much meat as the smaller-faster bullets. In most modern rifles the best accuracy range seems to be 165-190 gr. I wish we could get over the high velocity kick this country is on and get back to accuracy.
I can tell you first hand that the guys who make their living taking us Nimrods into the bush for their living after horned/antlered critters like to see a hunter show up with an old 30-06 and have a pocket full of 180gr ammo.
