As you are sighting in, your barrel will start to warm up usually gaining a more consistent POI. After you have your rifle sighted in and your barrel cools your POI will likely change correct? My question is when you go hunting and do not have a chance to warm up the barrel, what is the "likely" POI change I will notice from a cold bore to a warmed up barrel. I like to make quick, clean and effective 1 shot kills but dont want to have to worry about being inches off from my cold bore if I am shooting at an animal. Any help would be great.
