[QUOTE="MontanaRifleman, post: 340057, member: 11717"] That seems like an extreme difference, but some powders are very sensitive to temp changes. I have heard as much as 2 fps pre degree of temp with some. The difference in velocity wouldn't change the POI that much, but a difference in pressure might affect your barrel's harmonics. You might have something else going on too. How often have you checked your zereo and how consistant has it been? Mark [/QUOTE]
