Allen: Do you think the increased pressures in cold weather could be due to the rifle itself contracting very slightly, due to the cold, making the bore just a wee bit smaller? Sorta like a door jam shrinks and swells from moisture? I really have no idea, but the thought crossed my mind.......
I read an article by that guy McPherson in Precision Shooting that talked about pressures and cold weather;bottom line was everything just resisted ignition in the extreme cold...
I have had no trouble with RL22 in hot weather...nor in cold weather for that matter..
