[QUOTE="jeffro, post: 331342, member: 6780"] I know that cold powder and barrel produce lower velocity, but I didnt think it would make a 2 MOA difference at only 600yrds. I have shot in the cold weather before, it does make quite a big diference, but it didnt make that much difference. The Vel at 75degF was 2866fps. For the dope to work out for this drop, the Vel would have to have been around 2670fps. Almost 200fps less with a 35degF change in temp. [/QUOTE]
