Re: temperature sensitive powders?????
So, I have a load worked up for my .300 Win mag using H1000 and 200 grain Accubonds. It clocks just over 3000 fps in 70 degree weather. From what I am reading (and the reason I chose H1000) the temperature outside today (15 degrees F) should not affect the velocity of this load. I have no experimental data, but I am going to test it sometime in the near future.
Next, I have an itch to try something different this winter. I want to work up a load with the 180 Accubond. I have an 8lb caddy of IMR 4831 and an 8lb caddy of H1000. If I am looking for something that is going to remain stable should I even bother with the IMR 4831? [img]/ubbthreads/images/graemlins/confused.gif[/img]
