[QUOTE="ShtrRdy, post: 2065344, member: 40852"] This is a great discussion. I experienced this sort of thing a number of years ago. One other possibility that came to mind is the chronograph causing an incorrect measurement. The electronics and/or mechanics could change to introduce an error to the measurement. For example, in the case of an optical chrono or a Magnetospeed, under colder conditions, the sensors would be closer together due to the metal or plastic contracting. This would appear to the chrono that the bullet covered the distance between sensors quicker. Therefore the bullet must be going faster. [/QUOTE]
