powder temp sensitivity

[Brian Carlson]

I have a question for the forum members. I wonder if any of you have much experience with the temperature sensitivity of VVN165 or RL25? I am working up loads with these two powders at a temperature of about 35 degrees and wonder if they will be too hot (too much pressure) at early fall temperatures? Thanks, Brian.

If you don't get an adequate answer on this board you should e-mail the powder companies directly. I e-mailed VihtaVuoriOy and was happy with my reply.

Associated Question

The loading data books give maximum loads, as we all know. Reference is made to the problems of summer vs. winter, and the chamber pressure differences.

What is the ambient temperature at which the maximum load is figured? I don't recall reading this in any of the data books.
