From: "IG", [EMAIL PROTECTED] <<Actually pressure drops with altitude. What you were experiencing was the effect of reduced air density. Density drops with elevated temperatures and altitudes.>> Dave What I meant was an increase in cartridge pressure, not the ambient air pressure. The higher temperature of the powder means higher pressure within the case and a possible consequent increase in velocity. Add this to the less dense atmosphere and this is how I accounted for the decrease in drop of the bullet. As I said, the less than sympathetic handling by the airlines also could account for a knocked 'scope. Indeed, on returning home, I found the reticle of my scope was broken and the elevation adjustment cover was jammed and cross threaded. Could only have been done by a severe jolt, or the rifle being removed from its case and dropped. Of course, the carriers deny responsibility. As an aside, on my return, my rifle and that of my mate appeared on the luggage carousel. We picked them up and just walked away with them. Last year, they got lost at Heathrow, although we eventually got them back, they were returned to our homes without ever being checked either by customs or airport security. UK airport and airline handling of firearms is a joke, as anyone who has travelled abroad will probably testify. IG -- I find it varies depending on the airport, at Heathrow they usually come out on the carousel, at Gatwick Customs usually intercepts them. Steve.
