Two very successful powders for the .308 Win. are Hodgdon's Varget and IMR 4064. We are also getting great accuracy with Ramshot TAC but not sure if it is readily available.
45 gr. of Varget sends most 168 gr. bullets into one hole if the rifle is decent.
Another tip you could consider, we have standardized on one overall length - 2.830" and it works in every rifle so far.
I have an HS rifle in the Varmint model, it is a great shooter and will put five inside 0.5" if I can do my part.
Good luck with your loading and shooting.
N140, N150, N540, and N550 are all very hard to beat in 308 with the 167-168 grain bullet weight. You won't go wrong. RWS primers are very good with these powders, but I prefer the Speer-CCI BR-2 primer with these powders. Start with the manufacturer's recommended loads and work up to what your rifle likes best.
The rifle is a HS Precision Heavy Tatical, I have had it since November, and now I can buy the scope, rings and bases - Baer steel rings, bases and a NF 8 - 32 x 56
I am going to use the ladder method as break in for the barrel, starting very low and working right up, if break in is necessary this is one way I feel would easy the barrel in for the rist 100 or so rounds.
I will be shooting .1gn powder increments, not because I believe there will be any difference in .1gn loads, but to get mroe shot on paper so as to better plot the groups.
I'll post the results here as soon as I get this done, over the next month or so.
That much shooting during "break-in" is probably more of an excersize than a necessity, there are lots of different opinions on the necessity and benefits of breaking in a barrel. Bottom line, it is shooting - and that is why you bought the rifle. You are assembling a fine rig.
You will probably find that the .308 is very easy to develope accuracy loads for - I would also suggest Winchester large rifle primers if you can get them.

Re: best powder for .308win
I agree with Wyo on the scope and I agree with Wyo and Ian m on the powders. I think the only other super 308 powder would be RL-15. I have had 308's that didnt like Varget or 4064 but LOVED RL-15. Most 308's will do amazing things with Varget.

Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
