I use a 270W. It likes SMK at 135grn with 59.9grns of H1000 at about 2900ft/sec; which is very accurate for my setup (1/2" MOA). A good backup powder for it is H4831 at 56.0grns; almost as accurate. The MOA is correct, I spend a lot of time and money developing loads specific to my rifles; most of which are hunting style rifles. Again, this is what I use, and perhaps this will help you get in the right direction.
On a side note... The best powders I have personally had success with in bolt guns are Hodgdon brand. My favorites are H1000, H4831 and Varget. I do like other powders such as RL-15, but I use this in my precision AR platform. I will lean towards a brand if I get consistent results. However, when it comes to accuracy, you have to go with what the Scientific Method provides; evidence! Brand loyalty is no better than a religion. Let the brands out there earn loyalty through evidence. Good luck, be safe, and have fun.

if they do as well as all the reports I've heard from other hammer users then I'm sure I'll love em.
