I use a 270 win also. 130 gr bullets,great for deer. shot placement is the most important. Head shots should be avoided.I have personally had trouble with head shots. I managed to recover the animals. I have also had to shoot a couple of deer that some other hunter has tried to head shoot , blown the lower jaw off,and other parts of the head that weren' t fatel. What a waste.I now only shoot for the lungs or heart. For elk or moose I' d use 150 gr or 160 gr bullets out of a 270 win. I now use a 300 win mag 180 gr nosler parts.
