Makes sense.
However, I seem to become more aware of the roll on hot days than cold.
i think thats just cause its more common, ie you can even see it coming off the ground on really hot days.....looking through a scope i would think the heat waves coming off the barrel would be more pronounced in cold weather though.....i notice them more in cold weather but given what ive picked up in this thread so far, what i call cold weather and what the guys down south are calling cold weather aint the same
