A good friend in MT has been hunting with the same rifle since about 1950. It is a Rem 721 in 270 Win. He has killed more elk and deer than anyone that I know. It is a rare year that he does not kill both elk and deer. back in the day the deer would have been multi each year because of extra tags.

Always the same bullet, a 150 hornady with a load of 4931 I believe. If it works don't change it.
