I am going to be doing some reloading for a 270 WSM, 140 Accubond and 140 Sie SPBT and also would like to see good results with 257 Weatherby 117 gr. Sie SPBT.
I am a stick in the mud when it comes to new things, so please help me pick a good powder. Thanks!
I currently have some RL19, and H1000. Good choices?
 
The RL19 would be a decent choice for both. Not sure on the H1000 for the WSM.

For the WSM you might want to look at RL17.
For the Weatherby, RL23,RL26...
RL23 might also work well for the WSM.
 
My best results for the 270 WSM have been with Accurate MagPro, which is nearly identical speed as H1000. This with 140 gr bullets.
Reloader 19 is a little faster burning rate, and might do well with 130 gr and lighter bullets.
