[QUOTE="Alan Griffith, post: 146102, member: 4686"] Yesterday morning, while out getting my feet wetter w/ the '06 Ackley, the temp, of course, was increasing from upper 30's to about 60 when I quit shooting. I have a 25 yr old Bushnell Trophy spotting scope that came with a 16-36 powder adj occular lens as well as the 48x power lens I also bought at the time; I was using the 48x. As the temps increased, the mirage effect made it to where I could not make out hits on the clean white paper at anything 400+. My question is if optic quality will help or if even those shooters with big money/power scopes suffer the same due to heat induced mirage. If optic quality helps, how far out can you see hits on paper and at what temps can you do this to? If it doesn't help, are you just driving down, back and forth, a lot to the target to make heads or tails of what your rifle/load combo is doing? BTW, at 600 yd I was getting .75 to MOA groups. Probably nothing to some of you but I'm pickled tink! [/QUOTE]
