Ive used the 130gr .277 and the 110gr .277 and both worked well on antelope and deer. The 130's out of a 270 win @ 3100FPS did leave some very large exit wounds. The 110gr out of a 6.8 SPC contender did very well @ 2500 FPS...although the core did seperate from the jacket on the only one i recoved..but dead is dead.
