RE: .308 handloads
Vic,
I've had good results with the Hornady 150 grain Interbond and H-4895 and H-Varget. I use the CCI BR-2 primer in my .308 Win. With H-4895 the suggested starting load is 43.0 grains and the book max is 45.5 grains. With Varget, the starting load is 44.0 grains and the book max is 47.0 grains. Accuracy has been excellent with both powders.
Varget.
The 47.0 book max is a compressed load in my Lapua cases. In a 22" barrel velocities rreached 2780 fps.
H-4895.
In my rifle, Varget gave smaller five shot groups. H4895's groups run about 3/16" larger, but are still only 5/8". Velocities are right at 100 fps faster with H-4895. While the loads are not compressed, density is very close to 100%. This load makes me very happy.
I suggest that you start at the suggested starting load, and increase powder weight in half grain increments to the max load. I like to load three rounds per load and fire for group size. Once I've found the tightest grouping load, I'll load five rounds to a load and reload the tightest group load, and one step up and down and retry them. This will usually get you a very good hunting load. Good luck and God Bless.
