Anyone use this round for hunting deer, elk or larger game?

I've always used a .30-06 but last year I used a CZ 550 in 6.5x55 and got a nice mule deer buck and this year I did the same.

Low recoil, less noise and harvests deer as good if not better than the 06. Both years I used a load of IMR 4350 and a Hornady 140 grain SP. Hit the deer dead center through the lungs and he went about 20 yards and was done.

I was going to use the CZ and a 100 grain Nosler partition for antelope but I couldn't get it to shoot consistant. Maybe next year if I draw that is I will try some 120 Sierra spitzers and see how they work for antelope.

If I ever draw a Colorado elk tag should I stay with the 140 grain or go to a heavier bullet? BTW if I can't get within 150 or maybe 200 yards max I won't shoot.
