I was out shooting today with a temp of about -17c. windchill of -23c.
I just wanted to share some chrono #s with you guys to show the difference a cold bore shot makes. After a 3 round group the rifle would sit for a few min aloud to cool back down.
Take note of the spread difference between the first and than the 2&3 shots.

Interesting. Kinda makes you re-think 3rd groups when load testing.
