Max range you would shoot at game?
Depends on several factors of course. Game size, toughness, wind, caliber/cartridge I am using, etc.
That said, I have killed P-dogs and coyotes beyond the 1,000yd mark, elk at 890 and deer sized beyond 800yds. I have practiced to 2,000 yards and shot elk sized kill zone gongs at 1,500 to 1 mile.
