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 brass cases.

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 therefor 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.

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

Buffalo Bore loads their ammunition up to maximum SAAMI specifications, which delivers devastating performance on a wide range of game. Please note that this ammunition is not intended for older guns. It is made for modern post war firearms only, as some of the ammunition could damage older and weaker firearms. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Owner of Buffalo Bore Tim Sundles on Heavy 45 Colt Ammunition:

We knew that we could develop a couple standard pressure 45 colt loads that would feature a 255gr. Gas checked soft cast bullet at around 1,000 fps or a 200gr. Jacketed Hollow Point at around 1,100fps. We wanted loads that were substantially more powerful than today’s weenie loads, but that could be fired in ANY 45 colt firearm.

Both of these 45 colt loads are designed to be a heavy loading, yet be within standard (SAAMI) pressure. As such, both of these 45 colt loads are safe and recommended to be used IN ANY post-war 45 colt that is in normal working condition.

These loads are indeed heavy 45 colt loadings. You can fire them in any post-war firearm that is in normal working condition chambered for 45 colt without reservation. These loads will turn your Colt SAA or clone into a powerful carry gun. The cast load (item 3E) is gas checked and will not substantially lead your barrel.

See the below velocities.
