Running Target (movie, 1956)

In the Colorado Rockies, Sheriff Scott, heads a posse that is after four escaped convicts, and thought it is his sworn duty to return the men dead or alive, he is, as always, reluctant to kill his fellow man. He is accompanied by Jaynes, a tavern owner, who takes much delight in his telescopic rifle, and by "Smitty," a gas station held up the escapees and more than ready to show she can be as tough as any man, although she seems to have some other motive for getting to the leader of the convicts, Kaygo.
