Umarex® ARX® Ammunition represents the next generation of muzzleloading and airgun hunting technology. Precision-engineered at the pioneering PolyCase® Ammunition development lab, Umarex ARX ammo incorporates patent-pending innovation that enables extreme hunting performance. Constructed from an advanced polymer-copper matrix, the Umarex ARX SpeedBand™ and SpeedBelt™ bullets will revolutionize terminal performance in both muzzleloading and airgun hunting.
PolyCase ARX technology acts as a force multiplier in muzzleloader and airgun ammunition, simultaneously dispersing kinetic energy both forward and laterally. ARX non-expanding ammo provides maximum hydraulic displacement and terminal energy transfer to targets. This high velocity, flat-shooting projectile provides exceptional performance in mid and big-bore air rifles when combined with Umarex SpeedBand or SpeedBelt polymer sabots.
Umarex ARX Ammunition elevates pre-charged pneumatic air rifle performance into the 21st century with four of the most popular air rifle chamberings. The groundbreaking Umarex SpeedBand sabot was developed for use with Umarex ARX bullets in .357, .40 and .45 caliber while the base-style SpeedBelt sabot was designed for use with .50 caliber Umarex ARX ammo and performs flawlessly in both muzzleloaders and the new Umarex Hammer™.50 caliber big bore air rifle.
The polymer formulation of Umarex SpeedBand and SpeedBelt sabots creates a powerful seal in barrel lands and grooves, blocking the passage of air to swiftly drive the projectile down the barrel. Upon exiting the muzzle, captive air pressure on the sabot forces release of the high velocity, light-weight ARX ammo, which maximizes momentum and delivers un-paralleled terminal performance on target.

Practical Ammo

Jeff Fletcher:

Three years ago ammo was scarce and the prices went through the roof as shooters, fearful of the economic downturn and politics, bought up anything and everything on retailers’ shelves. This year, the supply—still waning in hard-to-get popular configurations—has expanded to include newer calibers, and prices for most hunting rounds have settled down. In addition, new ammo makers have joined the club with product that is both practical and plentiful.

NSSF Opposition Letter to Proposed Lead Ammunition Ban (AB 711)

Regarding the proposed lead ban in California:

First, absent sound science of an adverse impact to wildlife populations, there is no justifiable basis to restrict use traditional ammo. If sound science exists then wildlife managers (not legislators) should lead the identification of possible remedial measures available that adequately address the issue and implement the measure that is least costly to the sportsmen.


5 Yr. Lead Ammo Ban Fails To Reduce Levels of Lead In Condors

Despite a 99% compliance rate by hunters, there has been no reduction in condor lead posioning during the 5 years that the lead ammunition ban has been in place within the condor corridor.

.300 Whisper M&P15

S&W Introduces the M&P15 300 Whisper
S&W Introduces the M&P15 300 Whisper

Smith & Wesson Corp. announced that the Company has added a new extension to its Military & Police (M&P) Rifle Series with the introduction of the M&P15 chambered in .300 Whisper. As the first production rifle in the AR platform to be chambered in .300 Whisper (also chambers .300 AAC Blackout), the new rifle offers sub-sonic and supersonic capabilities while delivering consistent performance and accuracy.

Manufactured on the M&P15 platform, the semi-automatic rifle features a 16″ barrel constructed from 4140 chrome-moly steel. Both the forged 7075 aluminum upper and lower receivers have been coated with a Realtree® APG finish for optimal concealment during hunting applications. To aide in precise shot placement, the gas-operated rifle benefits from a 1 in 7.5″ twist, 5R rifling and a crisp single-stage trigger. Other standard features include a 10-round magazine, integral one-piece trigger guard, dust cover, forward assist and a six-position, collapsible CAR stock.

“As the popularity of the modern sporting rifle continues to grow, more hunters are seeing the advantages of taking these firearms into the field,” said Mario Pasantes, Senior Vice President of Marketing and Global Professional Sales. “The M&P15 300 Whisper gives consumers the ability to use either lightweight or heavy cartridges during hunting or recreational applications without changing rifles or barrels.”

Designed to operate with or without a sound suppressor, the M&P15 300 Whisper is equipped with a 5/8-24 threaded barrel along with an A2-style flash hider. The feed ramps and gas system have been optimized to run effectively with a full-range of factory loaded sub-sonic and supersonic ammunition, both suppressed and unsuppressed. The barrel’s twist rate is compatible with a wide variety of bullet weights from 110 to 220+ grains.

For enhanced reliability, the M&P15 300 Whisper features a chrome-lined gas key and bolt carrier along with a Melonite barrel. The optics ready platform is compatible with most sighting systems through the use of the picatinny-style equipment rail located on top of the upper receiver.

Pasantes continued, “With the introduction of the M&P15 300 Whisper, Smith & Wesson now offers over 18 different configurations of the modern sporting rifle. Each of these rifles has been engineered from the ground up to meet not only our expectations but those set by our customers. Offering exceptional accuracy, limited recoil and the ability to customize the rifle to meet individual preferences, firearms such as the M&P Rifle Series have earned a high level of trust within the hunting and shooting sports community.”

The M&P15 300 Whisper will also be available with a black tactical upper featuring a 10″ free-float quad rail and a Yankee Hill Phantom flash hider. The upper is compatible with any mil-spec AR lower.

Alexander Arms relinquishes 6.5 Grendel trademark


The 6.5 Grendel is an official SAAMI cartridge and trademark is relinquished. The Sporting Arms and Ammunition Manufacturers’ Institute (“SAAMI”) has adopted the 6.5 Grendel as an official SAAMI cartridge. As a result of the cartridge’s official recognition, Alexander Arms will relinquish the trademark “6.5 Grendel.”

Bill Alexander states: “One of the primary purposes of trademarking the name was to protect the integrity of the design. With the adoption of the 6.5 Grendel cartridge standard by SAAMI, the design is now protected, and any confusion in the marketplace as to the specification of the cartridge has been eliminated.”

SAAMI’s formal adoption of the design specifications for the cartridge has led Alexander Arms to announce that it will relinquish its federally-registered trademark and that “6.5 Grendel” to be the common commercial name for a cartridge that adheres to the specifications adopted by SAAMI.

Alexander Arms is proud that a cartridge of its design has received this important designation, and is pleased to take this important step in the continued market development of this breakthrough cartridge, which is perfectly matched to the AR-15 platform.

Blackout for the Win

300 AAC Blackout Used in Win at MultiGun Nationals

Staff Sargent Daniel Horner of the US Army’s Marksmanship Unit used the new 300 AAC Blackout cartridge to win first overall in the Tactical Optics division of the 2011 USPSA MultiGun National Championship, held outside of Las Vegas, Nevada.

300 AAC Blackout was launched by Advanced Armament Corp. and Remington primarily for the military as a way to shoot 30 caliber bullets from the M4/AR15 platform while using standard magazines, but is expected to see a lot of use for hunting, plinking, and home defense as well. The concept of putting a 30-caliber bullet in a shortened 223 case has been done before, but not as an industry-wide standard that anyone can make products for, royalty-free.

More below:

SAAMI, the industry standards organization, adopted 300 BLK earlier this year, and it now has broad industry support- with over 60 companies making products for it. Remington is leading the pack with the most types and highest volume of ammo available – 125 grain open-tip match with a custom Sierra bullet, 220 grain subsonic, and 125 grain AccuTip for hunting, law enforcement, and self-defense.

While this is one of the lowest-cost cartridges to reload for – Remington and AAC recognized that most people are not reloaders – so UMC ammo is planned to be out soon with a price of just $12.99 MSRP per box – substantially less than other cartridges that are a power upgrade from 223. And the use of the cartridge to win the Nationals while qualifying for “Major Power Factor” leaves no doubt about the potential for accuracy and the capability of some major punch.

Robert Silvers, AAC’s Director of Research and Development – and project lead for the platform, explained “People want to hunt with their AR, and 223 may not be legal in their state or they just may not like varmint-sized bullets – now there is a way to shoot 30 caliber from your AR while still using normal magazines with full capacity. Even the bolt stays the same, and all that changes is the barrel.”

Expect to hear a lot more about this cartridge as many more companies announce products at the 2012 Shot Show and throughout next year. For more information visit
