I have found similar to what H2OBUG speaks of. In the heat here in Texas I have found that with Ball powders it is best to drop at least 2 grs in the hotter days of summer shooting. Either that, or go to a target load. Rifles or Pistols. I use a mag primer with 2400 a lot. Many will tell you that is not needed but it seems to work.
Longshot is a powder that was not designed for pistols, but works in certain calibers and loads. The Powder is not supposed to be sensitive to the cold. But now just how cold I do not know. It has been since the mid 90s when we designed the powder.
This was discussed that the powder not be sensitive to cold since it was going to be used on Pheasants in Kansa and Nebraska in Winter. Sounds like I need to make a phone call.
As far as a target load,,, (WST) Winchester Super Target has proven to give better results than W231 in the 38 and 45 ACP. Event the SASS cowboys use it in their loads. I know this does not help for hunting.
Some folks will stay at home when the mercury drops. But for those who can do it and want to,, this is just another excuse to go shooting when it is freezing out there.
We used to have a shoot on New Years Day in the morning. It was over well before noon. It was called the "Hangover shoot". There were some years it really did test you and your loads.
