My source says it was over 100 yards but not sure yet by how much.
Either way, that is some fine shooting.
When I shot PPC I did all my practice from 50 yards, if you can make that everything closer is easy. Rural shootings are sometimes different from urban shootings, in that, the ranges are extended. The US Border Patrol for example does get into shoot outs at extended distances.
How is someone shooting an unknown weapon at you from 200 yards less a threat than at 10 yards? Depending on the circumstances, shooting back may or may not be the wisest course of action.
My rifle and pistol are tools, I am the weapon.
