My cousin has killed a traincar load of deer with the cheap old Remington CoreLokt 100gr. bullets/ammo. It works on the corn-fed fat Missouri deer, and I'd expect it to work equally well on NH deer, too. I've only killed one deer with a .25/06, and I used a 100gr. Sierra Prohunter, it worked as expected, a quick dash of 30 yards, and it fell in a heap.

You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.
