Apparently this thread brought out all the clowns who think non-temp-stabilized double base powders aren't temp sensitive.
I suppose it's possible that the laws of chemistry were repealed specifically in your rifles, and powders with the least temp stable chemistry in common use (we don't do triple base powders and cordite any more) are somehow stable for you. If so that's great.
But reality is that there's a hierarchy in terms of powder stability by chemistry from most stable to least:
Temp stabilized powders (recent ADI series, IMR Enduron, and the RL-16/23/AR-COMP series)
then
Single based IMR-type powders
then
Double base not temp stabilized (which includes the RL series with the exception of 23 and 16, TAC, and a bunch of other powders like H335 etc.)
then
Triple base powders, cordite, and certain other obsolete powders
There's really not all that much to it, but of course lots of marketing chaff being blown by companies with an interest in selling non-stabilized powders. In the end I don't give a flying [bleep] what you put in your rifle, but the facts are the facts.
