Hello Guys / Gals, Can we please start a discussion regarding Cold Bore Accuracy and the process of figuring out what to do and how to do it? I'm a Hunter, not a BR guy, so groups are cool, but in my mind, my first bullet is as important as my first and only arrow. With a bow, nothing heats up and it POI really doesn't change, and I'd very rarely get a follow-up shot opportunity, so for all intensive purposes, what happens with that first shot either fills the freezer or leaves an animal to suffer and me with a very guilty conscience . . . thus, I focus ALL of my efforts towards Perfection On One! So, can someone please explain the theory behind cold bore accuracy, and then, your specific steps towards figuring it out. Is this something that's done at 100 yds, or at all ranges? Can it be done in the summer (early morning hours)? Can it / should it be done if there are other variables present (wind / moisture / thermals / etc)? I would assume that it should be done only at intended-elevation for hunting location . . . ? Can you get a basis for cold bore accuracy at lower elevations and then fine-tune it up in the mtns? Thanks everyone.
