I'm like Sam that is minimal damage for a 22-250.I have tore bunnies up worse than that with .22 rimfire.That canine had better watch it or he's going to end up with scope eye.
I'm afraid no chance with the autographs, you should maybe try ebay. Anyway, I thought they all lived in the States now; you've got more chance of meeting them than I have.
Thanks for the welcome.
