Best Powder For 7mm STW

[track]

Hey Guys!
A simple question. What is the powder that you use for your 7mm STW for the 140 or 150 grain bullets?
Thanks!

7828, H1000, H570, H5010, Retumbo, H450, RL22 and 25, basically look to powder on the slow end of the scale. Personally with 140gr bullets I get the best results from 7828 and RL22 in mine. With 160, 175 and 195gr bullets I do better with RL25 and Retumbo. FWIW - dan

I thought RL-22 resulted in awesome velocity with 140's

My 7mmstws all did very well with IMR7828 and 140gr bullets.

All my STWs have liked a different powder best, but H1000 has been good in all of them.

I never shot much of the 140 grain bullets in my STW's, but I did shoot a lot of 160 Partitions.
Best powders were Retumbo, H1000, Reloder 25, and the out-of-production H5010.
I never tried us869 or Ramshot Magnum, but they would be candidates as well.
