This is Underwood's maximum offering for the .500 S&W Magnum revolver. The 700-grain hard cast lead projectile fills the cylinder nearly to capacity, leaving you with ammunition that pushes the boundaries of what's commercially available in the handgun world. With a muzzle velocity of 1200 feet per second and muzzle energy of 2239 ft-lbs, the ballistic performance rivals heavy rifle rounds and shotgun slugs.
Underwood switched from their previous Hi-Tek coating to the new Black Cherry polymer finish, which provides thermal stability across extreme pressure and temperature conditions. The coating prevents lead-to-bore contact, essentially eliminating lead fouling that can accumulate over time. It also resists gas cutting and provides wear protection when firing at full power levels.
The wide flat nose design means this bullet doesn't expand on impact. Instead, it maintains its shape to drive straight through dense material and heavy bone structure. That's what makes this load ideal for big game scenarios where you need to punch through thick hides and muscle without deflection. The hard cast construction ensures the bullet stays together under extreme velocity.
Underwood loads these rounds in nickel-plated brass cases with boxer primers. The nickel plating improves feeding reliability, won't tarnish in storage, and makes cleanup easier if you decide to reload. Flash-suppressed powder is standard across the Underwood line so your low-light performance stays sharp. Everything meets SAAMI specifications for safe chamber fit in any stock .500 S&W Magnum revolver.
The recoil is extreme. Underwood specifically recommends loading only one or two rounds in the cylinder at a time if firing through a 4-inch barrel due to the excessive recoil impulse, which can loosen even tight crimps and cause projectiles to creep out of the case. Longer barrels (6 inches or more) are easier to manage, though felt recoil remains substantial.
Yes, they're loaded to SAAMI specifications and will chamber safely in any stock .500 S&W Magnum revolver. The 700-grain load uses nearly all available case capacity, so the cartridge is longer than lighter loads, but this doesn't affect function or safety when the firearm is properly maintained.
Absolutely. The cases are boxer-primed and designed for reloading. Nickel-plated brass actually offers reloading advantages over standard brass, including resistance to tarnishing and easier cleanup. Just follow standard .500 S&W Magnum reloading practices and data.
Yes, these rounds are safe for suppressors. Lead bullets don't pose the same wear concerns that some jacketed rounds can create inside suppressor baffles, making the hard cast flat nose design compatible with sound-reducing equipment.
