Nosler Partition is available in 160/.277 but not sure why he would need these for deer hunting?? I agree the 130-140's are all I have used for deer hunting in the 270. I had excellent results from the Hornady 140gr BTSP. I would also look at the 130 gr Interbond or the spire points of 130-150 if he wants to shoot hornady. By far my favorite deer bullet in my 270 was the Nosler Ballistic Tip, deadly accurate and always reliable. So you could also try the 130 or 150 gr SST if your wanting to stick with Hornady but similar design.
