This 223 Rem cartridge from Winchester’s Super-X line of ammunition sports a 55 grain projectile, which is the most common bullet weight for its caliber. The bullet is special because its core is made of tin rather than lead -- that means you may enjoy varmint hunting with this round wherever toxic ammunition is banned, including California. Its partial jacket exposes this bullet’s soft core so that it will expand rapidly when it hits a target, which coupled with the round’s staggeringly fast 3,050 fps muzzle velocity ought to be enough to seriously ruin any woodchuck’s or prairie dog’s plans for later that day. The bullet’s flat tip means it will function very well in rifles with tubular magazines, and also makes it ideal for shooting paper targets, through which it will punch out clean and easily scored holes. This round also offers a reliable Boxer primer, factory fresh brass casing, and clean burning powder.
