Load testing/Ladder testing in Cold Weather?

[JBinMN]

Inquiries have been made to Alliant & Hodgdon regarding if there is a list of "Temp. Sensitive" powders for their products that is available to the public, thru their "contact" system. I am awaiting a response from both.

I am also trying to continue to research thru search engines for sources to gather as much info as I can. I have made some progress. Not enough for me to proceed yet, but some progress anyway.

JB...what exactly is the test plan? Objectives? Etc...?

Sorry, I'm kinda lost after all this?

Charlie, my goal was to gather info in general, in regard to "temp stability" of powders, from the folks here who may know, or could lead me in the right direction to know more, & then work with "reduced loads" if it was viable, once info was obtained that might help.

That did not happen.

----------------------------------------
As far as an update about my inquiries to the powder makers. I have rec'd one.

I am not allowed to break confidentiality of the contents of that email, as per the reply "I" rec'd.. ( You will have to ask on your own, if you want more than what I am about to share.).

The person who replied to me did not offer anything more than I already know. Although, I think I could share that using a fast powder, like Clays for example, might be a worthy choice of powder, it being a faster one in the burn rate tables, since all powders are temp. sensitive in some manner or the other...

That is the "gist" of the short reply I rec'd. I have learned more from "researching" the internet than I rec'd in the email. YMMV on that. Maybe someone here "knows" someone and could get a more informative reply than I did... I am not impressed, BTW. But then again, they did not have to reply at all.


I have nothing else to share...

I have now rec'd return emails from the 2 powder mnfrs about temperature sensitivity in their respective powders. The powders I have mentioned before in this topic, are "Temp. Sensitive".

The Alliant Rep. was specific about the "Temp Sens." with 3 rifle powders they make, as NOT being "temp sensitive". Their "rep" was more informative with some specific powders, than the other rep..

Thanks for your interest & well wishes. I will reply with more info as it is available to me & what I may find in any testing I do. I am still considering whether I will do this sort of Cold Weather/Reduced load, since I am also going to start testing the effects of temperatures on some powders in "book"/manuals suggested loads from Start(min.) to Max., in a year long project.( as per another topic)
I may "piggy back " the 2 projects, but not sure yet. My release of info depends on how much interest there is in what might I find.


I also still welcome any helpful suggestions in regard to doing this sort of thing.

Thanks again!
