This is 44 Mag Winchester Supreme Platinum Tip 250gr. Hollow Point Ammo. This ammo has the patented reverse taper bullet jacket like the Talon series of ammunition. It also has a nickel plated heavy wall bullet jacket and two part hollow point cavity for uniform bullet expansion. This is a great defense or hunting round. A speedy 1250 feet per second velocity out of the bore and the delivery of more than 850 ft. lbs. of energy (867), means you have a very serious contender in the field with this round. That doesn’t even take into account the great hollow point design labeled as the Platinum tip in part because of the looks but also because it represents the pinnacle of innovation and engineering for the Winchester USA ammunition line. It comes packed in 20rd. boxes.
