The company who brought to life "the Gun that Won the West" is the same company who today continues to supply sportsmen with the best sporting ammunition in the world.

In December, 1980, the company's board of directors authorized the restructuring of the Winchester Group to allow Olin to better focus more of the company's resources on Winchester's sporting and defense ammunition business. With this restructuring, Winchester's U.S. sporting arms business, which had been part of the company for nearly half a century, was set up as a freestanding operation. In July, 1981, it was sold to the U.S. Repeating Arms Company in New Haven, Connecticut, which now produces Winchester brand rifles and shotguns under license from Olin Corporation.

In 1991, Olin's Winchester Division again played a part during a war. When the Persian Gulf War broke out, Winchester provided a large amount of the ammunition used by U.S. troops during this conflict.
