Funny. When I purchased my first high powered hunting rifle in 1970 it was a 788 Remington in 308W. All the press said "the powder" for it was IMR 4064. Honorable mention were WW 748 and BLC2. I tried 4064 and with 150 and 165gr. bullets and never found anything but lack luster performance accuracy wise. I bought a pound of 748 and BLC2 to give them a try.....748 turned out to be magic. I still have 1/2 of that can of BLC2....
47gr. of 748 behind a Hornady 150gr. interlock has been a deadly combination for all these years. Accurate, burns clean, decent velocity without beating up me or the gun, and it kills deer like the hammer of Thor....I like it. I killed a nice little buck with that same rifle last year, same load, and it will still put 5 of them into an inch or so at 100yds. I only have a straight 4x scope on it and I just can't shoot any better than that.
I have heard about the powder being sensitive to cold weather. I have not found that to be so....down to -9F. I have about 12 lbs of 748 on hand. I use it in the 7x30 Waters, some in the 223R and of course my 308W. At my age I think I have enough to last me "a while."
