Well, an interesting day at the range today. The test was to see if I could get 2800fps out of my SPS .308 using a 168g Nosler Ballistic Tip. I started with 44.5 grains of Varget and worked up a half grain each group gaining about 50fps each time I went up a half grain in powder. My final loads were 46grains of Varget with an OAL of 2.84 and I achieved 2840fps without any signs of pressure on the spent cases. The upper left target in the picture is 44.5g. The upper right is 45g. The lower left is 46g and the lower right is 45.5g of powder. One thing I did not do was separate the cases by weight (I'm using winchester brass and winchester large rifle primers). I say this because I noticed rather large variations in velocity and they coincided with what looks like fliers on the lower two groups. When I got back to my shed and weighed the spent cases I had as much as 7 grains difference in some of the case weights. Next trip I will separate my cases by weight and we'll see if I can't make a 1 hole 5 shot group at 100 yards (I totally believe this is possible with this gun/load combination). For reference the orange dots are 3/4". Looks like it's going to be an excellent hunting load!
