I'm still not sure what to think about a "po' man's bore gage" someone sent from a gun forum. Say's it's supposed to tell me how thoroughly shot-out the barrel is. What is it? An inert 30-06 round. Stick the bullet in the barrel, and how far it goes is how worn the rifling is. I'm scepetical, but the "Magic Ouija Bullet" says I have a little life yet. The only REAL test to to train myself up enough to hold a good group, and see if the rifle can keep up. Still, many folks swear by it, so... we'll see. I really shouldn't knock it, it was sent as a kind gesture. I really do appreciate it, too. I'll keep it, might want to use it again.
