Speer DeepCurl handgun hunting bullets in 454 Casull, 300 grains (Speer part no. 3974), electrochemically bond the DeepCurl jacket to the lead core, the process Speer uses to build what it calls the toughest, most accurate handgun hunting bullet possible. Pre-formed petals on the hollow point expand reliably and consistently, and the bullet’s high weight retention ensures deep penetration on heavy-bodied game rather than a bullet that sheds mass and stalls early. Paired with one of the hardest-hitting production revolver cartridges available, this 300-grain loading gives 454 Casull hunters a projectile matched to the biggest game the cartridge is meant to take.
