The new Hornady 150 SST tip bullet / load sounds like it would be great for deer!!
Personally I like the Remington 180 grn jacketed round nose factory load. Worked great on the first Alaska moose I ever shot, when I was about 12 years old.
A lot of people live in areas that in addition to deer they have black bear and possibly hogs. Personally I want to carry a tougher and/or heavier bullet for the chance I run into that big bear or hog!
Wish Federal would put out a 165 grn Partition load! Like Jocko suggests, that would be a great all-around load for the good ol' .300 Savage!!
