hopefully one of you knowledgable chaps can answer this for me.
How much affect does barrel temperature affect your zero/ bullet placement? If there is a tangible difference, what would be the process for zeroing for a cold barrel? Is it a case of zeroing as normal, waiting for it to cool, firing, seeing where it lands ad adjusting accordingly... Then repeating?
May seem like a daft question but I'm new too shooting rifles in general and my experience isn't huge.
