Hi all. My IDPA load is a 200g LSWC over 5.5g of 231 with W large pistol primers. Out of my Baer PremierII, this gives me a velocity of 870 and a power factor of 174 (IDPA power factor for .45's is 165).
The couple of times I have chronoed this load it has been during a hot summer day with temps between 75-85 degrees. What will happen to the velocity of this load when I start shooting it in 50 degree weather? Will it go up or down, and why? Any estimates on how much of a move up or down for 50 degree weather? Thanks in advance.
Regards,
Frank
