Which powder to start with

I got a STW built a couple months ago and have shot 3 boxes of Nosler factory ammo through for the brass. I would like to start reloading for it and would like to start with 160gr Nosler Accubonds. Any recommendations on which powder to start with to start working up a load ? Any help would be greatly appreciated.

Hodgdon H1000 or Hodgdon Retumbo.

I've had really good luck with H1000.

rl22,rl25 for mid weight.... rl33,rl50 for heavies.... retumbo, h1000, and h50bmg if you like to srpinkle a bit of single base around. 7828 will work for mid weight too but the pressures tend to be up a bit by the time to get to good speed.
Ball type slow burners can work well too but some bores (like mine) won't eat them well; it's hit and miss with those in this cal and the temp sensativity makes non stabilized stick powders look good.
