Cold barrel pressure/velocity? - 05/16/17
Do shots from a cold barrel typically generate higher pressure/velocity? When chronographing loads it seems (although I haven't collected data) my first 1 or 2 shots are higher velocity (100-150 fps in a 7 mag) faster than after the barrel warms (and expands?).
If this occurs it seems it could be pronounced if you shoot if 50F degree weather and then hunt in 10 degree weather.
I did a quick search and didn't find any info.
Thanks,
David
