Swift’s A-Frame Heavy Revolver load in .357 Magnum (brand part no. 10003) pairs a 180-grain bonded-core bullet with a muzzle velocity of 1,363 feet per second, giving revolver and lever-action shooters a controlled-expansion option built for serious penetration. The A-Frame design bonds the front core to its jacket while a partition separates it from a solid rear section, so the bullet expands through its front half while the rear stays intact to drive deep. Swift rates the A-Frame to begin reliable expansion around 950 feet per second, well below this load’s muzzle velocity, and to retain roughly 97 percent of its original weight even after opening to about 1.65 times its starting diameter. Because it is loaded to work in both revolvers and .357-chambered lever guns, this round gives hunters and backcountry carriers one loading that performs the same from either platform. Twenty rounds ship per box for hunters who need dependable expansion and penetration on heavy game.
