shooting the spine out of an arrow?
I have heard from time to time of people claiming to have "shot the spine out" of an arrow. I assume this refers to basically weakening the arrow somehow.
I have a set of Axis arrows I've been shooting relentlessly for a year and a half or so. And I'm starting to have real trouble getting good groups or any repeatable performance out of them.
IS there really such a thing as "shooting the spine out of an arrow?"
