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 Xtreme Defender is based on the popular Xtreme Penetrator product line. The XD ammunition has an optimized nose flute, total weight, and velocity to achieve a penetration depth up to 18 inches with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollow point comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet, expansion is achieved despite being shot through barriers. The solid copper body ensures that wallboard, sheet metal, and automotive glass will have no effect on the Permanent Wound Channel. 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.

The Underwood nickel plating process provides several key benefits including; improved feeding in all actions of firearms, enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals. Until the development of the Ducta-Bright 7a process, nickel plating casings often limited the number of reloads as compared to raw brass. It was claimed that nickel plated brass casings embrittled the brass therefore making it less desirable for reloaders despite the ease of cleanup that nickel plating offers. In addition, ammunition engineers raising concerns of using nickel plating in very hot +P or magnum loads found that traditional nickel plating often cracked deep-drawn cases, or worse, lead to a total failure. This new process eliminates any concern, to the shooter or reloader, of hazard or ability to re-use the brass.

Features

• Reduced recoil.
• CNC machined from solid copper to overcome barriers to penetration
• Radial flutes that force the hydraulic energy inward to build pressure
• Minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers

Lehigh Defense XD Ammunition features the proven Xtreme Defense bullets. This high quality ammunition is perfect for hunting or pest control. The lead free projectiles are safe to use in any environment with no risk of lead contamination. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.

The Xtreme Defense (XD) Technology is based on the popular Xtreme Penetrator product line. The design goal was to achieve the same barrier performance and massive permanent wound cavity and reduce the penetration depth to coincide with an individual’s personal comfort level. It was a goal Lehigh did not meet; it was a goal they blew out of the water!

The XD Bullet has an optimized nose flute, total weight, and velocity to achieve a penetration depth range of 18 inches with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollowpoint comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet, it is near barrier blind, ignoring wallboard, sheet metal, and automotive glass.

Lehigh Defense was able to accomplish this quantum leap in terminal performance at the same time while reducing recoil. The terminal performance achieved is quickly approaching that of 5.56 rifle performance and that is an incredible feat.

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

Features

• A permanent wound cavity (PWC) that is 2 times greater than any expanding bullet
• Radial flutes that force the hydraulic energy inward to build pressure
• Minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers

G2 Research is a premium self defense, and environmentally conscious defense/hunting ammunition manufacturer. G2 Research’s vast understanding of material properties and utilization of complex geometries renders predictable and consistent results that maximize the effectiveness of its solid copper/lead free projectiles. The G2 Research R.I.P. (Radically Invasive Projectile) features a unique one hundred percent copper petaled-trocar design which gives it the ability to not only penetrate deep into a target but also fragment in fluid. Upon entering a gel or fluid the petals break from the base and create individual wound channels as the base continues on course. This penetration and separation delivers not only a maximum shock wave but wound path as well. In years of ammunition design there has always been a trade off between mass and velocity to accomplish the goal of effective stopping power. G2 Research added a third variable with the patented trocar design. The surgically designed trocars offer better barrier penetration thus maintaining a higher velocity when hitting a target, transferring more energy into the target. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

IMPORTANT INFORMATION ABOUT THE HEADSTAMP ON THIS BRASS: Due to limited supplies of brass, Buffalo Bore has begun loading +P and +P+ ammunition in brass that may not be indicated as such on the headstamp. Example: 9mm Luger +P+ ammunition may be designated as 9mm Luger +P or simply 9mm Luger on the headstamp.

Buffalo Bore loads their ammunition with the highest quality components available to maximize the performance of the ammunition. This ammunition is safe to use in all 40 S&W chambered firearms with a fully supported chamber. Most Glock 40 S&W do not have a fully supported chamber do not use this ammunition in Glock 40 S&W or other unsupported chamber pistols. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Owner of Buffalo Bore Tim Sundles on Buffalo Bore Heavy 40 S&W +P Ammunition:

All Buffalo Bore Heavy 40 S&W +P loads use flash suppressed powders that give high velocities at low pressures. Since over 90% of all human shootings in the USA happen in low light, we believe that flash suppressed powders are a potentially life saving advantage – you don’t want to be blind after you fire one shot in a life threatening, high stress situation.

There is such a variety of 40 S&W pistols in public use that we will not determine what pistols are compatible with which 40 S&W +P loads – this is your responsibility! We will add that this ammo is safe in pistols that use a fully supported chamber. Please read the safety notices below. The first one is taken form the Speer #13 loading manual. The second is taken from Hodgdons #27 loading manual.

SAFETY NOTICE

“Some pistols chambered for the 40 S&W cartridge may not provide complete support of the case head. If this condition exists, normal pressure loads such as those shown here can cause the case wall to bulge or rupture at the unsupported point. Contact your firearm manufacturer to determine if your pistol completely supports the case head, or ask a gunsmith to inspect your pistol before using it with ANY ammunition. It is the gun owners responsibility to know his firearm and its capabilities and limitations.”

40 S&W WARNING

“This data is intended for use in firearms which fully support the cartridge in the chamber. Use of this data in firearms which do not fully support the cartridge may result in bulged cases, ruptured cases, case head separation, or other conditions which may result in damage to the firearm and/or result in injury or death of the shooter or bystanders.”

Glock happens to chamber their 40 S&W pistols without a fully supported chamber and both of those above safety notices are likely aimed at Glock. I know of no other 40 S&W handguns being sold in the US that don’t have fully supported chambers. If you really want to shoot our 40S&W ammo in your Glock, have an after market barrel that uses a supported chamber, dropped into it. This is a fairly common practice and will give you the safety margin needed to fire our ammo in your Glock. It will also likely give you more velocity than the factory Glock barrel. I personally own two Glock Model 23’s. Both of mine are going to get after market barrels dropped in so that I can use this excellent ammo in them. The issue of Glock pistols not having a fully supported chamber is with the 40 S&W cartridge only, not 45 acp, 10mm, 9mm or 380 auto. While Glocks chambers are not fully supported in any of those calibers, only the 40 S&W brass is weak enough in the web for it to be a safety issue. I REPEAT, only the 40 S&W is a safety issue with chambers that are not fully supported. You do not need to be concerned with this issue when using our 45acp+, 10mm, 380 auto+P or 9mm+P or +P+ ammunition in Glock pistols.

Check out the velocities below that I shot with these loads in several modern pistols that I own. We don’t believe that test barrels are a very real way of determining real life velocities out of real life guns that you will be using. So, as with all of our ammo, we use real firearms to determine real velocities.
