I went to my local reloading store today and they were out of 4895, as one would expect right now. They were also out of 4064 and Varget and their AA2520 got recalled. So I got a pound of W748. Anyone have any tips on using it in a 150 or 175gr .308? I've heard it's pretty temperature sensitive and here in MN we got from -20F to 95F+.
