Description
If you're looking for a heavyweight .357 Magnum load that actually delivers on performance, this is it. Double Tap's 200-grain hardcast solid ammunition is built from the ground up for hunters and anyone serious about woods protection. The wide flat-nose gas-checked hardcast bullet is designed to penetrate deep without relying on expansion, which makes it ideal for hunting situations where you need reliable, consistent terminal performance.
What Makes the Double Tap 200gr Hardcast Stand Out
The bullet construction here is what separates this from your standard .357 loads. These hardcast projectiles are alloyed with metals like antimony to create a bullet that won't deform as it travels through bone and tissue. That means maximum penetration and a wide wound channel from the flat-nose profile. At 1200 feet per second from a 4-inch barrel (or 1315 fps from a 6-inch), you're getting 640 foot-pounds of muzzle energy that carries downrange—still maintaining 563 foot-pounds at 50 yards from a 4-inch gun.
Double Tap .357 Ammunition Performance Data
Velocity numbers vary with barrel length, which is why Double Tap publishes specs from both common platform lengths. From a 4-inch Ruger GP-100 you'll see 1200 fps, while a 6-inch S&W 686 pushes the load to 1315 fps average. The 200-grain weight means recoil will be stout, especially in lighter revolvers, but that's also a sign you're working with real stopping power. This is purpose-built for deer, hogs, and situations where you need a gun that will do its job in the field.
The brass cases are reloadable for folks who reload their own ammunition, and each round comes quality-checked before leaving Double Tap's Utah facility.

Frequently Asked Questions
Will Double Tap's 200 grain hardcast work in my .357 Magnum revolver?
Yes, this ammunition is designed for all standard .357 Magnum revolvers. The 1.580-inch overall length works fine in modern revolvers like the Ruger GP-100, S&W 686, and Security Six. Keep in mind the 200-grain weight and high velocity will produce significant recoil, especially in lighter or compact models.
What's the difference between hardcast and regular lead bullets?
Hardcast bullets are alloyed with metals like antimony to make them substantially harder than standard lead. This means they won't deform or expand as they penetrate, which gives you deeper, more consistent wound channels. For hunting larger game or in thick brush, that controlled penetration is exactly what you want.
Can I reload Double Tap brass cases?
Yes, the brass cases are reloadable and marked with Double Tap's headstamp. Many reloaders appreciate the quality and consistency of the casings for hand-loading their own ammunition.
How does velocity change with different barrel lengths?
Double Tap publishes chrono data from two common barrel lengths so you know what to expect. A 4-inch barrel gives you 1200 fps, while a 6-inch barrel produces 1315 fps. Longer barrels burn more powder and develop more velocity, which affects both power and trajectory at distance.
