[username J]

Is there any published loads for the 6.8 western using nosler 170 gr BTs?
TIA

Not that I'm aware of. I had to guess a bit with them from Hodgdons data. It develops pressure at a lower charge weight than the 170 gr Berger. I just started low and went up slowly.

That’s the only published data that was close I could find. They have a start load of 52.7 gr. Was that your start point?
What did your Max load work out to?

Looking at the data you must be looking at H 4831 sc which has a starting load of 52.7 gr. I haven't tried that powder yet but did work up with Magpro and Retumbo and the 170 gr Ballistic tip and ended up a couple grains less than the Berger data. It could be my gun too since I am a bit less with the 175 gr Sierra TGK than what Hodgdon calls for. Your gun might be a bit different so you'll have to work up slowly and watch for signs of pressure. If it were me I would start with 52 gr and go from there. Lots of guys here can help with where would be a good place to stop if you haven't questions. Please keep us up to date on how it's going.
