Federal Barnes Expander 454 Casull 250 grain solid copper hollow point P454XB1 ammo pairs a Barnes all-copper expanding bullet with the substantial 454 Casull revolver chambering. Its one-piece projectile avoids the separate lead core and jacket of an ordinary JHP, making bullet construction central to this big-game hunting load.
Barnes Expander bullets use a hollow nose formed in copper to promote expansion while retaining a solid shank. Federal lists 1,530 fps for this 250-grain ammo. Although the monolithic design is associated with controlled expansion, actual recovered diameter and retained weight depend on the test conditions and cannot be inferred from the material alone.
The combination of 250-grain copper construction and a defined factory velocity makes it a distinct option from heavier hard-cast bullets intended for a different terminal behavior. Federal packages 20 nickel-cased rounds of this ammunition for hunting applications. A 454 Casull revolver's cylinder length, sight regulation, and the manufacturer's cartridge guidance are worth confirming before use.
