 That is valuable information. Hodgdon propellents have always worked well for me, and it's good to know their Extreme series behaves itself in the cold, as advertised. Thanks for posting this!
 
 
 
 P.S.  -19F. at my house the day before yesterday. Snot stops dripping at about -10F., I think it is....

Having been in an outhouse at -19, I can tell you that snot isn't the only thing that won't drip.

Good information. 
 
I read once that Black Hills used Ramshot powder in their factory loads.  Would anyone happen to know for certain?
