[QUOTE="steeltraps, post: 947385, member: 74752"] I see your point as well. I have though about puttung the whole gun, 338 lapua in the deep freeze and trying to shoot it after it got cold. The nightforce scope would fog up, but i could shoot it , with the magneto speed chrono i use for field work on. Do you think this would closer mimic frezzing mornings in north alabama? I see how ambient temp. plays into the sensitity of the load. If i sight in gun at 50/67/29.13 then i right it down= fps =3010 fps .Then i may shoot this gun=load again at 30/67/29.13 i also right that fps down= 2995 fps. So i would come to the conclusion that 30 degrees colder = 15 fps slower. To me its an easy fix. I always carry my kestel 4500 and my ballistic program in my range=hunting bag with my Vector 4 rangefinder. I get what Jmden is saying about metal expanding and contracting. What do you guy think about me doing a WHOLE gun deep freeze then shoot deal? Then what about putting the rifle in the truck on the dash of the winsheald and testing it? I have a 300 yard range that is with-in feet of my yard and deep freeze. Do you guys feel this would be a better test of RL-33 temp. sensitivity? [/QUOTE]
