Cold bore shot

[021411]

Bare with me for a second concerning cold bore shots. I know this question may sound absurd or TOS-ish but is there a specific range of temp that a "cold bore" is? I know many first shots are critical be it hunting or killing/man stopping. Is there an accepted way of practicing this at the range? Shoot one round and let it cool for how long?

Cold bore shot is:

Dirty barrel (at least one round fired.. I do 2)

Barrel temp at ambient. (ie, same temp as the air. 65F air/65F barrel)

I use a digital strip thermometer.

The "cold shooter" is usually the biggest factor to the "cold bore" shot...

Thanks for the tip. I can put the regular thermometer back in the medicine chest.

Interesting question. A few years ago I attended a Tactical Rifle Match, where the first shot of the day was at an 8" steel plate at 600 yds (known distance) to be shot prone off your bipod or pack. Only one shot allowed, no sighters. Temp was about 35 degrees, wind quartering at about 6 mph.

Anyway, we had 24 shooters, and 23 misses. And yes, I missed too...

How many of you hit low?

Really no way to tell. Just a steel plate hanging from a frame via a chain and the backstop was nothing but dense woods and a gentle up-hill slope. But if I had to guess, most of us missed low.

How many of you hit low?

Excellent question. That was my first thought.

Carlos Hathcock taught cold bore shooting by having the student fire one single shot and recording the result and the range conditions. One shot and one shot only for that day. One shooter related how he didn't understand why until he realized he was collecting data on how he and his rifle performed for that single, often critical shot

Depends on the rifle for me. I have a .243 bolt gun that's consistently ~1.5 MOA high on the first shot of the day, and a SCAR H that's just about the exact opposite.
