You can go to Nosler's website and click on the reloading data page then pick 300WSM with 150gr bullets. It show's there they have data with RL15 and RL19 for the 150grs. Also Hodgdons web should have some data as well. Good luck

You might want to get on Alliant site as they have reloading data for 150gr bullet using R-17 they listed max @ 69.3gr and you want to start 10% below that. I'm using R-17 in a 270WSM/300WSM in the 300WSM I'm shooting 165gr AB /168gr TSX and 180gr Speer bullets.

Well good luck

I'm not sure who's going to list R-17 in their reloading manuals.

I've been loading R-17 for almost a year now in several cartridges, 243, 6mm, 260 and have played with it in a 22-250 with good results.

As for load data, there's not much to be had, but it's a very good powder and well worth developing some loads for it to see how it works for you. I've been loading long a long time and know how to develope loads. I haven't bought a manual since 1971. I luv the results I've gotten with R-17, It's the best powder by far I've found for a 260 with 1:8 twist.
