New Ultralight Arms Light Mountain Rifle in 338 Winchester Magnum. Forbes' most extreme production offering applies the LMR's aggressive weight reduction to the 338 Win Mag. The result is a dangerous-game-capable rifle under 6 pounds — lighter than most standard hunting rifles in non-magnum calibers. Recoil is significant and technique is essential, but the weight savings for Alaskan or British Columbian mountain hunters pursuing bears are without equal. Type: Rifle Action: Bolt-Action Caliber: 338 Winchester Magnum Capacity: 1 Year introduced: 2008, USA Weight: 60 oz Overall length: 44" Status: Active Intended use: hunting, dangerous game, mountain hunting
