Hi i have a Walther dom and leup 20x50 combi my one from room temp 18 to -0, I see a change of 10ftsec in speed, i get to my shoot one hour before and let it cool down to outside temp and then crono it then check zero,what i do see sometimes is i have to add a couple of clicks on the longer shots as i think the pellet slows down faster in the colder thicker air.I dont think my scope shifts in that temp range as most of my range finding ties up with what the other lads say.
