I mainly use the 40 gr Nosler BT's in my 223's driven at 3700, I have also used the 50's just not as often. With both bullets I have had great success - usually just an entrance hole and a dead coyote. The 40's in particular drop them like they were pole-axed. My favorite coyote bullet by far.

223 Rem, my favorite cartridge - you can't argue with truckloads of dead PD's and gophers.
