I have been loading for my .270 Winchester for 62 years. My pet load for deer, antelope, black bear is Nosler 130 partition and H4831 at 3200fps. When I go for elk I load 150 gr partitions at 3000. These loads are all chronographed and safe in my rifle. Have killed elk to 350 yards and antelope to 400. In earlier years I used the surplus 4831 in 50-lb kegs but have used H4831 for many years now.
