well, i use Rem 150 gr. Core-lokt PSP. First of all, because it's what I've been shooting since I can remember and I've never had any trouble with it. Second, because its cheap and I go through a box a season. If I had to pick a bullet that I have seen perform well it would be Winchester ballistic silvertips 168 gr. I've had exit holes when shooting deer in the shoulder the size of softballs so it does perform. One doe I got this year, the bullet never entered the ribcage, it just blew throught the bottom of the brisket. I don't know how I killed that deer but it only ran 20 yards... it works miracles for me, my dad, and granddad. I've seen sooo many deer killed by one i don't know what else there is. the best would have been when my dad killed 3 deer with two shots at 300 yards.
