Grizzly Cartridge Company was founded in 2003 with an inherent focus on quality and innovation. Each step of the manufacturing process undergoes strict personal inspection by the company’s founder to ensure the absolute best product possible.

This ammunition is loaded with a Cast Performance Long Flat Nose Gas Check bullet. Cast from virgin alloy, Cast Performance bullets are produced in extremely precise and consistent LBT style molds. Optimal hardness from heat-treating prevents fragmentation on even the toughest hide and bone. New production, non-corrosive in reloadable brass cases.

While taking advantage of state of the art testing equipment, this high performance ammunition by Underwood is field tested using popular, real firearms that customers are most likely to own out in the real world with all the elements you would experience. If for some reason Underwood Ammunition fails to meet performance expectations, Underwood stands by their product 100% and will make sure the customer is satisfied with every purchase. This ammunition is new production, non-corrosive, in boxer primed, reloadable nickel plated brass cases.

The Lehigh Xtreme Penetrator bullet features progressive nose geometry, which allows for deep, straight penetration while creating a permanent wound cavity diameter exceeding that of most expanding bullets. To top it off, the bullet is solid copper and is able to overcome barriers to penetration; environmentally friendly, target unfriendly, very unfriendly, downright obnoxiously unfriendly. The magic happens with the nose design where the radial flutes force the hydraulic energy inward and then as the energy is restricted, it accelerates outward creating high pressure spikes damaging surrounding tissue. Kind of similar to sticking your thumb over a garden hose. The permanent wound cavity of the XP is from two to four times greater than what a flat or ball nose bullet generates and often larger than traditional expanding bullets. So what you get is exceptional penetration coupled with a larger permanent wound cavity. The solid copper alloy construction will not deform when contacting hard surfaces like a lead jacketed bullet will do nor will it fragment as some hard cast lead bullets are prone to do. What it will do is overcome surface barriers and penetrate straight and deep while creating a massive wound channel.

Suppressor Safe— The projectile is machined from solid bar stock. This is not a frangible bullet produced from powdered metal.

Features

• Progressive nose geometry for deep, straight penetration
• CNC machined from solid copper to overcome barriers to penetration
• Radial flutes that force the hydraulic energy inward to build pressure
• A permanent wound cavity that is 2 to 4 times greater than flat or ball nose bullets

Custom-grade ammunition from the factory. Built to the tightest tolerances for peak performance rivaling and sometimes surpassing handloads in many guns. Loaded with the Flex Tip eXpanding bullet, the same used in the Hornady LEVERevolution cartridges, this custom load features a soft polymer flex tip that’s tough enough to stand up to a jacketed bullet, but soft enough so it won’t dent the primer of the round in front of it or cause accidental firing in a lever gun.

The patented Flex Tip bullet features an interlocking design that keeps the core of the bullet and the jacket together creating a deeper penetrating, more humane kill. Not only that, they offer controlled expansion, enhanced accuracy and the delivery of flatter trajectories. These bullets are safe to use in all tubular magazines, as well as any other firearm. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Hard cast flat nose bullets are non-expanding, powerfully penetrative bullets that are designed with your woods defense needs in mind; whether fending off wild hogs or black bears, the hard cast flat nose bullets are consistently effective in taking down any wild animals that you may encounter. In contrast to the round nose non-expanding bullets, the flat nose bullets are able to pierce through dense bodies of mass while maintaining their nose forward position, which is optimal for maximum penetration. All non-jacketed lead bullets, whether it may be cast, hard cast, wad-cutter, etc. “smoke” to some degree due to the wax/lube needed in the manufacturing process. Underwood Ammo’s hard cast feature a “Black Cherry” coating. Equipped with enhancements from the previous Hi-Tek coating. The “Black Cherry” coating is a  polymer-based compound; its thermal stability allows it to handle more than any other coating today. The coating will protect against gas cutting with a high degree of wear and abrasion resistance. The “Black Cherry” coating prevents lead to bore contact, thus virtually eliminating lead fouling. All firearms can safely function with this upgraded projectile. To include polygonal rifling (Glock). All of Underwood Ammo rounds utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.

Features

• No plastic burning smell
• Thermally stable
• Resistant to weathering and chemical degradation
• Strong mechanical and tensile strength properties
• Self-lubricating
• Able to withstand high pressure conditions
• Able to withstand high heat conditions
• High degree of wear and abrasion resistance
• Reduced friction resistance
• Good flame retarding properties
• Coating prevents lead to bore contact thus virtually eliminating lead fouling
• Shoot higher velocities without lead fouling

Note: The 700 gr 500 S&W ammo is unique in the sense that it has an exceptional amount of recoil. For those brave enough to fire them in a barrel 4″” or shorter, Underwood recommends only putting one or two in the cylinder at a time. The excessive recoil impulse in these smaller firearms can loosen even the strongest of crimps in cartridges waiting their turn in the cylinder, potentially causing the projectile to “”creep”” out of the case. Yes you may shoot these in a snub nose 500 S&W, but if you’re loading a cylinder full you might find yourself fighting physics.
