Re: cold bore shot through chrony 40fps higher than next four shots
I am no expert but I found most of my work up loads are faster from a cold bore but I can find a powder charge around max that tightens up the velocity and that load so far has bean the most accurate anyway, so you may want to change your powder charge slightly and see if the spread changes. Of course it's true when hunting the first one is the only one and anything else is an act of desperation, but you should know how it will act in case you need it. Life happens and it isn't always pretty. Good luck.
