.257 Weatherby Magnum 120 Grain Nosler Partition~100% Hand Loaded !!

$105.99

.257 Weatherby Magnum 120 Grain Nosler Partition~ The .257 Weatherby Magnum is a .257 Caliber (6.35 mm) belted bottlenecked cartridge. It is one of the original standard length magnums developed by shortening the .375 H&H Magnum case to approx. 2.5 in (64 mm). Of the cartridges developed by Roy Weatherby in 1944, the .257 Weatherby Magnum was known to have been his favorite, and the cartridge currently ranks third in Weatherby cartridge sales, after the .30-378 Weatherby Magnum and the .300 Weatherby Magnum.

The .257 Weatherby Magnum is among one of the flattest shooting commercial cartridges. The .257 Weatherby Magnum shares the same cartridge case as the .270 Weatherby Magnum and the 7mm Weatherby Magnum. The .30 Super Belted Rimless H&H manufactured by Winchester served as the direct parent cartridge for the case design. The .257 Weatherby Magnum was one of the first cartridges which used the shortened, blown out and necked down .375 H&H Magnum case and served as the forerunner to the standard length magnum cartridges such as the 7mm Remington Magnum and the .338 Winchester Magnum. There has been some speculation that Roy Weatherby may have used the full length .375 H&H Magnum case if he had slow burning powders available today when the cartridge was designed.

Our 100% Hand-Loaded .257 Weatherby 120 grain Nosler Partition rounds are loaded with extremely tight tolerances, producing highly accurate, consistent and reliable performance with each and every shot! Proprietary load formulas and our hand loading techniques offer the finest ammunition on the commercial market today.

Nosler’s special lead alloy, dual core provides superior mushrooming performance at virtually all impact velocities. The Partition’s fully tapered copper jacket gradually thickens along the bullet’s axis, controlling the core’s mushroom for controlled, uniform expansion. An integral partition separates the bullet’s two cores, holding two-thirds of the bullet’s original weight in the rear core to fuel a deep penetration every time. Special crimp locks help the bullet resist deformation, even with the heaviest of magnum loads. Each Partition bullet is designed by Nosler engineers to give you the optimum length, weight, and ogive design for each caliber to give you maximum flight and terminal performance. Minimum impact velocity: 1800 fps. There aren’t a lot of true disadvantages to this bullet because it is truly “debugged” technology. Newer bullets are very specialized for certain uses – some are for large game, some are for long range, and some are just for penetration or expansion. The Nosler Partition is more of a “jack of all trades and master of none” at this stage in bullet technology.

    The Berger VLD design incorporates a sharp nose that allows the bullet to penetrate 2″ to 3″ before it starts to expand. After the initial expansion, the bullet will shed between 40% and 85% of its weight as shrapnel into the surrounding tissue (internal organs). The combination between the shrapnel and the hydrostatic shock produces a massive wound cavity within the vital area that will be 13″ – 15″ long. This massive wound cavity results in the animal dropping fast since most go into shock after such a tremendous blow. Those animals that don’t go down immediately will soon succumb to blood pressure loss and/or organ failure producing a quick ethical kill.

    25-06 Remington .25-06 Remington 115 Grain Berger VLD Hunting~100% Hand Loaded !! Rounds Per Box: 20
     $65.99
    Add to wishlist

    .25-06 Remington 115 Berger VLD-Hunting~ The .25-06 Remington had been a wildcat cartridge for half a century before being standardized by Remington in 1969. It is based on the .30-06 Springfield cartridge necked-down (case opening made narrower) to .257 caliber with no other changes. Nominal bullet diameter is 0.257 inches and bullet weights range from 75 to 120 grains. The cartridge has less felt recoil than a 30-06 in a similar weight rifle, due to the lighter weight bullets used. Shooters who are recoil sensitive will find the recoil from the 25-06 bearable, but not pleasant enough to shoot all day long. This cartridge is not quite as powerful as the .257 Weatherby Magnum, usually running 200–300 ft/s (61–91 m/s). slower with a given bullet weight.

    .25-caliber bullets typically have high ballistic coefficients without being heavy. This characteristic, when combined with the large case capacity of its parent .30-06 case, allows relatively high muzzle velocities without heavy recoil. The combination of high ballistic coefficients with high muzzle velocities give the .25-06 a very flat trajectory as well as retaining kinetic energy down-range. The .25-06 is generally considered to be a good round for medium-sized game such as deer and antelope because of its combination of substantial kinetic energy and moderate recoil. The addition of a flat trajectory makes it particularly popular in plains states where the open fields can require longer-range shots on game, as this flatness tends to minimize range-estimation errors by the hunter.

    Our 100% Hand-Loaded 100 grain Berger VLD-Hunting rounds are loaded with extremely tight tolerances, producing highly accurate, consistent and reliable performance with each and every shot! Our proprietary load formulas and loading process create the finest round of ammunition available on the commercial market today we feel. If you don’t load your own ammunition- let us do it for you!

    The Bullet-

    Image result for berger vld hunting

    The Berger VLD Hunting bullet line features Very Low Drag (VLD) bullets that have the highest possible ballistic coefficient designed for 300 yards or more, the design incorporates a sharp nose that allows the bullet to penetrate 2″ to 3″ before it starts to expand. After the initial expansion, the bullet will shed between 40% and 85% of its weight as shrapnel into the surrounding tissue (internal organs). The combination between the shrapnel and the hydrostatic shock produces a massive wound cavity within the vital area that will be 13″ – 15″ long. This massive wound cavity results in the animal dropping fast since most go into shock after such a tremendous blow. Those animals that don’t go down immediately will soon succumb to blood pressure loss and/or organ failure producing a quick ethical kill.

    .243 Winchester 75 Grain Hornady V-Max~ Our 100% Hand-Loaded .243 Winchester 75 grain Hornady V-Max rounds are loaded with extremely tight tolerances, producing highly accurate, consistent and reliable performance with each and every shot!

    The .243 Winchester (6×52mm) is a popular sporting rifle cartridge. Initially designed as a target/varmint round, it may be used for animals such as coyotes, blacktail deer, whitetail deer, mule deer, pronghorns, and wild hogs. It can also be used against larger animals such as black bears and elk but is sometimes said to be “too light” for such large animals. Rounds of at least 90 grains are better suited for hunting larger animals while rounds less than 90 grains are more suitable for varmints. The .243 is based on a necked down .308 cartridge case. It is very popular with target shooters, metallic silhouette, and long range shooters, because of its accuracy and low recoil. This cartridge was first introduced in 1955 for the Winchester Model 70 bolt-action and Model 88 lever-action sporting rifles and quickly gained popularity among sportsmen worldwide. Just about every major manufacturer offers rifles chambered in .243.

     

     

    The Bullet:

    Hornady V-Max Bullets feature a polymer tip which enhances accuracy and promotes devastating expansion. The tip raises the ballistic coefficient for faster velocity and also acts as a wedge, initiating bullet expansion. The flat base creates in-flight stability for long-range shooting.

    Hornady’s swaging process creates precise formation of the core around the tip of the bullet, creating a build-up of energy which contributes to its phenomenal performance.

    .300 Weatherby 180 Grain Nosler AccuBond~ Roy Weatherby already had experience with other custom cartridges such as his own .270 Weatherby Magnum when he created the .300 Weatherby. Like most of his other magnum cartridges, this is based on a blown-out .300 H&H Magnum case, using the signature Weatherby double-radius shoulder.

    It is often debated which came first the 300 Winchester Magnum or the 300 Weatherby Magnum, the Weatherby was first 1944 vs the Winchester was introduced in 1963. With the .300 Remington Ultra Magnum being introduced in 1999. Historically, Weatherby claimed that this is the most powerful .30 caliber magnum rifle commercially available, but the recently introduced .300 RUM and Weatherby’s own .30-378 Weatherby Magnum are now more powerful. One could say, the .300 Weatherby was 50 years ahead of its time as it has only been recently that suitable optics and range finders for long range hunting have been available to the public at affordable prices.

    The .300 Wby is in common use by big-game hunters all over the world.

    Choice Ammunition has taken our 100% hand-loading techniques and produce an extremely accurate, highly dependable round for the .300 Weatherby in this load. Our loading tolerances are only matched by passionate hand-loaders in their own loading rooms.

    The Bullet

    Through an exclusive bonding process that eliminates voids in the bullet core, AccuBond couples Nosler’s proven copper-alloy jacket with its special lead-alloy core. The result is a bullet that flies true, penetrates deep and retains its weight, without causing extensive barrel fouling. The unique white polymer tip resists deforming and initiates expansion on impact. Nosler’s Solid Base at the rear of the bullet acts as a platform for large diameter mushrooms.

    .223 Remington 40 Grain Nosler Ballistic Tip!~ The development of the cartridge which eventually became the .223 Remington was intrinsically linked to the development of a new lightweight combat rifle. The cartridge and rifle were developed by Fairchild Industries, Remington Arms and several engineers working toward a goal developed by U.S. Continental Army Command (CONARC). Early development work began in 1957. A project to create a small caliber high velocity (SCHV) firearm was created. Eugene Stoner of ArmaLite was invited to scale down the AR-10 (7.62 mm) design. Winchester was also invited to participate. The parameters requested by CONARC were:

    • .22 caliber
    • Bullet exceeding supersonic speed at 500 yards 
    • Rifle weight 6 lbs
    • Magazine capacity of 20 rounds
    • Select fire for both semi-automatic and fully automatic use
    • Penetration of US steel helmet one side, at 500 yards
    • Penetration of .135″ steel plate at 500 yards
    • Accuracy and ballistics equal to M2 ball ammunition (.30-06 M1 Garand)
    • Wounding ability equal to the M1 Carbine

    Our 100% Hand-Loaded 115 grain Berger VLD-Hunting rounds are loaded with extremely tight tolerances, producing highly accurate, consistent and reliable performance with each and every shot! Our proprietary load formulas and loading process create the finest round of ammunition available on the commercial market today we feel. If you don’t load your own ammunition- let us do it for you!

    Nosler Ballistic Tip Bullets are designed for violent expansion upon impact. The bullet is tipped with a polycarbonate tip which rapidly drives back forcing the thin jacket to expand and fragment. The heavy base prevents deformation during firing and the boat-tail design increases the ballistic efficiency of the bullet.
