Re: Cold bore shot is usually high
What I normally did in the past was shoot 3 groups of 5 rounds and adjusted my scope accordingly to the best group. I would wait a 24 to 48 hrs to depending on my schedule and shoot one round. I would see where the bullet hole was and I would adjust one more time to that shot. This is how I would adjust for cold bore shots when hunting also. After the 1st cold bore shot I would shoot 4 more shots and usually there was little adjustment to be done if any. Dialing my scope was not necessary.
When hunting you always know when the opportunity rises where your 1st shot will go since your scope is adjusted for a cold bore shot.
