- The .223 WSSM (Winchester Super Short Magnum) is a high performance rifle cartridge developed by Winchester in 2005. This round has significantly more power than the traditional .223 Remington, making it an excellent choice for hunters and target shooters looking for a bit more punch. The increased velocity of this round also makes it suitable for longer distance shooting, giving it extra potential as a varmint or predator round.The .223 WSSM is available in bolt and auto-loading actions, so you'll have plenty of options when choosing your rifle. It can also be used for deer hunting if the correct bullet type is chosen and the appropriate range limitations are observed. Furthermore, many ammunition manufacturers offer specialty rounds such as frangible and training cartridges that are specifically designed for this caliber.
