Re: 308 Win loads
Varget has worked very well for me. If you look at the VarGet bottle, they recommend 46 grains with a Fed 210M primer and a Sierra 168 gr BTHP.
This exact load shoots in the .2's out of my Rock barrel
45 Grains of Varget with the 168 gr Barnes X Triple shock BTHP shoots in the .3's
44 grains with the 165 gr Barnes X bullets shoots in the .4's and .5's.
Great powder for .308's IMHO
Distance is not an issue, but the wind will make it interesting!
