The Accurate Magpro that I'm using in my 7mm RM seems pretty temp. stable.That sucks to hear about the Ram Shot not working out for you. I was going to try that Mag Pro. I am trying to find a powder for my 300WSM that will give me the speeds I want. Hopefully this new to me barrel will give me the speed I want with H4350. RL17 I am finding to be very unstable in temp changes greater than 10 to 15 degrees. This could cause problems sitting in a field groundhog hunting.
My bad, just realized that Ram Shot and Accurate were two different companies. Have you ever tried the Accurate powder line?

The Accurate Magpro that I'm using in my 7mm RM seems pretty temp. stable.
The batch of 162 gr SST that I loaded lasted all year. Shot great a 72*F and also at 20*F two weeks ago. My hunting rifle took a serious thump on the hunt so the group was 3" to the left. But still on the money vertically.
I'll stop now before I divert this thread any further.
Sorry Yall.
