VV N560 temp stability

[jonnyviceroy]

For anybody who’s ran N560 what was your experience with temperature sensitivity? Currently in the process of compiling components and got some N560. I was curious anyone’s experience I know it is not listed as one of their temperature “insensitive” powders, but have read mixed things on its stability and to what extent it fell one way or the other.

Did you ever get any more feedback or data on temp stability? I'm thinking of using the stuff myself.

Yes thank you I forgot to report back here but I did an initial test and have now used it for a year and have been super happy with it.

In my opinion, it is not temp stable at all. Roughly 1.8fps per degree Fahrenheit.

Loads below are 59.0gr N560 in 6.5 Sherman Short 20" barrel with 135 classic hunter:

3 rounds in ice bath (34°F) yielded:
2821
2818
2835

3 rounds that were baked on a pickup dash with the windshield defrost on max (102°F):
2958
2948
2946

So roughly 130fps increase over 68°F increase
