One shot, One kill.
(not counting "mercy shots" while they were kicking and flopping on the ground)

With a Ruger #1, you only get one shot, so make it count or don't shoot.
(As some say: A single shot will make a rifleman out of you.)

Never had one (deer) run more than 50 yards.
Black Bear never went far either.
Dad used one of his on elk..... same thing.
