It was just about 100 years ago that outgoing Teddy Roosevelt penned some details to the Winchester Repeating Arms Co. about a .405 rifle he wanted to tote to Africa once he wrapped up his two terms as president. And now, on the 150th birthday of the famed hunter and conservationist, Winchester Ammunition is commemorating his presidency and that gun with special Roosevelt ammo. "He was a hunter extraordinaire and a big Winchester fan," says the company's Glen Weeks. At about $40, the nickel-plated .405, .30-.30, and .45 Colt bullets packaged in specially designed boxes featuring tr hunting scenes are more souvenirs than game and target shots. They will show up in stores this month. Weeks wouldn't say who's next in the commemorative run, but it won't be errant shotgunner Vice President Dick Cheney. "Maybe 100 years from now," he joked.
