Temp stability - RL22, n165, Magpro, IMR7828 - 11/23/14
Has anyone ever done any testing with the above powders for temperature stability? I remember reading years ago when Mule Deer tested RL22 and got significant POI/velocity changes.
I am looking for a load in my 280ai that is temp stable. I tried some of the Hodgdon Extreme powders, H4831 and 1000, but velocity was not impressive. I kept adding powder to increase velocity and accuracy suffered.
So, has anybody tested RL22, n165, 7828, or Magpro at temps 70+ and down to zero?
