20 Rounds of 140gr Expander .357 Mag Ammo by Federal

Whether you’re defending your life with a revolver or putting dinner on the table with a lever-action rifle, this 357 Magnum ammunition by Federal Premium is up to the challenge. Federal’s Minnesotan-made ammo is loaded with Expander solid copper hollow point projectiles by Barnes of Utah!

The Expander is made of only one metal: copper. That’s why the bullet won’t pollute the environment. That’s why the bullet won’t leave lead residue on a barrel’s rifling. That’s also why the bullet is so tough – malleable copper exhibits virtually perfect weight retention during high-velocity penetration, so it stays intact enough to pierce thick hide or fabric and keep on tunneling all the way to the vital organs.

The Expander’s most impressive performance is its terminal expansion. It erects six razor-sharp cutting petals which wreak havoc on surrounding soft tissues while simultaneously anchoring the bullet within its target to reduce the chance of over-penetration.

Federal loads this ammunition with smooth-feeding and corrosion resistant nickel-plated brass cases, as well as the clean-burning propellant charges the 140 grain bullets need to reach a muzzle velocity of 1,400 feet per second out of a 6” barrel.
