At that time, I was using three 50 grain pellets behind that Expander. And had shot some groups at 200 yards that wererunning about 6to8 inches with the open sights. My biggest concern was a completly unknown amount of bullet drop - and whether there was enough horsepower to get good expansion.Anyway, it felt like a "Hail Mary" at the time - a shot I might have launched at a wounded animal getting away, but not at an unsuspecting elk.

Little side note: next morning the same group of cows came back. Got a 125yard shot this time .
