I had my bow sited in early in the season when the temperature was in the 70s. I practiced yesterday, temperatures in the 20s, was grouping up and right of the bulls eye by 6" at 30 yards. It also appeared that the alignment may have changed, as the arrows appeared to have some wobble.

I am wondering if:
- the colder temperature is changing the bow alignment
- arrows fly differently in colder temperature
- my sites got bumped

Has anyone else seen this? Thanks,
