347 $1.00 Off**
The Underwood Ammo .500 S&W Magnum 420 Grain Solid Monolithic Nickel Plated Brass Cased Pistol Ammunition is not for the faint of heart. This round, produced by Underwood Ammo, promises bone-crushing power and deep penetration, making it a serious contender for big game hunting and a last-ditch defense against truly formidable threats. I was immediately drawn to the monolithic copper construction and the nickel-plated brass casing, a combination suggesting both reliability and raw stopping power.
My need was simple: I wanted a load that could reliably penetrate thick hides and bone on dangerous game animals. In the past, I’ve used traditional lead-core rounds, but I’ve always been concerned about lead contamination and potential bullet fragmentation on impact. The promise of a solid copper, lead-free projectile intrigued me.
Upon receiving the ammunition, the first thing I noticed was the weight of each round. The nickel-plated brass casings gleamed, and the Underwood Ammo name was cleanly stamped. Compared to similar rounds, like the Hornady 500 S&W Magnum 350 grain XTP or the Buffalo Bore 440 grain Lead Free, the Underwood Ammo offering stood out due to its heavier bullet weight and solid monolithic design. I chose it specifically for its penetration potential, hoping to achieve complete pass-throughs on large game.
My initial reaction was a mix of excitement and healthy respect. This wasn’t just another cartridge; it felt like a tool designed for a specific, demanding purpose. I was eager to see if it lived up to the hype.

First Use Experience
I tested the Underwood Ammo .500 S&W Magnum 420 Grain Solid Monolithic Nickel Plated Brass Cased Pistol Ammunition at a private range in Montana, using a Smith & Wesson Model 500 revolver. The weather was dry and cool, around 50 degrees Fahrenheit, with a slight breeze. The recoil was significant, as expected from a .500 S&W Magnum, but manageable with a good grip and proper stance.
The ammunition performed flawlessly in the first session. I fired at various targets, including paper, ballistic gel, and a thick block of wood to simulate bone. The rounds consistently penetrated deep into the gel and wood, showing no signs of deformation. The recoil, while stout, felt more like a push than a sharp snap, likely due to the heavier bullet weight.
There were no malfunctions or misfires, and the nickel-plated cases ejected cleanly. The only real surprise was the sheer power of each shot; the sound and felt recoil were significantly more pronounced than with lighter .500 S&W Magnum loads I had used previously.
Extended Use & Reliability
After several months of use, the Underwood Ammo has proven to be exceptionally reliable. I’ve put roughly 200 rounds through my revolver, and I haven’t experienced a single failure to feed, fire, or eject. The nickel-plated cases still look new, with minimal signs of wear or tarnish.
The ammunition has held up well in various weather conditions, including a particularly wet and muddy hunting trip in the Pacific Northwest. I made sure to clean my revolver thoroughly after each use, but the ammunition itself showed no signs of corrosion or degradation. Compared to my previous experiences with other .500 S&W Magnum loads, the Underwood Ammo stands out in its consistent performance and durability. It has instilled a high level of confidence in its ability to perform when needed most.
