Cold vs Warm shooting

[JFB]

For those who range shoot a lot, just curious how much, if any, difference a ML or riffle will shoot when sighted in at fall temperatures and then later shot in freezing temps where the barrel and load have been in frozen conditions? (I'm not talking about a hot barrel effects from shots, just effect from outside temps). Had a discussion with someone who was saying the frozen pressure of the load changes the shot, etc.

Within 100 yards, I don't think the POI change, would be enough to worry about. On deer I have killed, it was not a factor.

At average hunting distances its minimal out past 5-600yds you will start to see effects. In the dessert where 80 degree changes in 12 hrs are common we never really worried about it until past 500m. With muzeloaders the powders are more susceptible to temp changes because they are not encased but with shorter max ranges it still doesn't amount to much of anything.The only exception I have found to this is the Jim shockey gold powder in my limited experience and testing I found as much as 6" in elevation variation at 150yds between 70 degrees and 0degrees. But this was also back when I used powerbelts and I know the ring on them contracted in the cold and that may have played a part in the fluctuation as well.

There's another thread on this I started that has some great inputs on it...just in case you want to look for it
