300 Win Mag Ammo
A powerful, accurate cartridge used for everything from big game hunting to long-rane competition to police sniping, the .300 Winchester Magnum ammo is a hard-kicking round derived from the even more powerful (and even harder-kicking) .375 H&H Magnum. It also has the notable advantage of being compact enough to fit in the non-magnum rifle actions of proven rifles like the Remington 700.
.300 Win Mag ammunition fire a medium weight 165-200 grain bullet (competition bullets can reach up to 220 grains for stability) at a muzzle velocity of just over 3,000 feet per second. Soft point loads offer excellent performance against all types of North American game, while Sierra MatchKings and other precision bullets dominate the competitive arena.
One of the more interesting weapons chambered in .300 Win Mag is the M2010 Enhanced Sniper Rifle, which is based on the M24 rifle. The M2010's use of this powerful chambering enables American snipers to strike targets at longer range than those possible with .308/7.62 NATO rifles in difficult environments like Afghanistan.

Winchester Deer Season XP 300 Win Mag 150 Grain Polymer Tip - 20 Rounds
$49.85Manufacturer Winchester Condition New Bullet Weight 150 Grain Bullet Type Polymer Tipped Use Type hunting whitetail deer Casing Type Brass Quantity 20 Ammo Caliber 300 Winchester Magnum Manufacturer SKU X300DS Primer Type Boxer Magnetic No UPC Barcode 020892221598 Cost Per Round $2.49 per round Winchester's Extreme Point (XP) projectile design, utilized in this Deer Season XP ammunition, ensures that the massive impact energy of the .300 Win Mag caliber is properly directed into the vital areas of big bucks, elk, and moose. The copper-jacketed bullet weighs in at 150 grains, has a drag-resistant shape for aerodynamic performance, and wears a large-diameter polymer tip up top which is intended to increase the size of the initial entry wound. Upon impact, the ballistic cone is drive back into the alloy lead core causing calculated deformation for maximum ballistic trauma.
A toothed cannelure at the bullet's midsection slows the rate of expansion and secures the bullet's jacket to its lead core; this effort allows the bullet to retain weight and momentum as it punches through the thick breastplate of a game target. Each bullet is crimped into a reloadable brass casing that hosts a precise load of clean-burning powder along with a non-corrosive Boxer primer.

Federal 300 Winchester Magnum 165 Grain TSX – 20 Rounds
$49.85Manufacturer Federal Condition New Bullet Weight 165 Grain Bullet Type TSX Use Type hunting big game, hunting whitetail deer Casing Type Nickel-Plated Brass Quantity 20 Ammo Caliber 300 Winchester Magnum Manufacturer SKU P300WR Primer Type Boxer Magnetic No UPC Barcode 604544647853 Cost Per Round $2.49 per round Accurate. Lethal. Lead-free. The Barnes TSX makes a perfect bullet for any 300 Winchester Magnum cartridge you would fire during a serious hunt! And that bullet only becomes better when Federal Premium complements it with their high-quality components and loading practices.
The TSX is made of pure copper. It can’t deposit lead residue in a barrel’s rifling. It also reduces copper fouling by virtue of its Accu-Groove channels, which minimize the amount of bearing surface that comes into contact with the bore. The clean-shooting TSX features a precision heel radius, which simply gives propellant an extremely uniform surface to exert their energy against. Once the 165 grain TSX is airborne, its sleek frontal profile secures a G1 ballistic coefficient of 0.398. That’s why its trajectory to 500 yards ought to rise no higher than 18.2” above the barrel.
The TSX’s monolithic composition also benefits penetration. The rugged bullet doesn’t shed significant weight as it plows into its target at high velocity, which is how it retains the momentum requisite for a deep wound channel. The TSX also doubles its diameter during penetration by undergoing rapid expansion: four separate and exceedingly injurious cutting petals!
Nickel-plated brass cases are always a welcome touch. In addition to reducing friction during feeding and ejection, nickel wards off corrosion that could have interrupted seamless functionality. -

Federal 300 Winchester Magnum 200 Grain Terminal Ascent – 20 Rounds
$57.85Manufacturer Federal Condition New Bullet Weight 200 Grain Bullet Type Polymer Tipped Use Type hunting big game, hunting whitetail deer Casing Type Nickel-Plated Brass Quantity 20 Ammo Caliber 300 Winchester Magnum Manufacturer SKU P300WTA1 Primer Type Boxer Magnetic No UPC Barcode 604544659429 Cost Per Round $2.89 per round The Terminal Ascent. It is essentially Federal Premium’s Trophy Bonded Tip, but reengineered so it can undergo full terminal expansion at velocities up to 200 fps lower than its predecessor. Whether you’re hunting long-range or up-close with your 300 Winchester Magnum rifle, this ammo won’t let you down.
The Terminal Ascent doesn’t miss an opportunity to conserve its own velocity. The bullet owes its flat, wind resistant trajectory to its sharp Slipstream Tip, drag-minimizing AccuChannel groove technology, tapered base and concentric jacket. All together, these features heighten the 200 grain Terminal Ascent’s G7 ballistic coefficient to 0.304 (G1 0.608). Zero in at 500 yards and witness a trajectory that tops out at 18.4”.
The Slipstream tip is surrounded by a thin jacket mouth and anchored in the center of a dense lead core. It triggers wide expansion even when it reaches its mark with relatively little kinetic energy. The Terminal Ascent doesn’t fail at close range, either, as its core and thick copper shank are fully bonded. The bullet’s thick solid copper base also assures the momentum requisite for wide expansion coupled with deep penetration.
Carefully matched primers and propellant charges provide reliable performance. Nickel-plated brass cases supply smooth feeding and enhanced corrosion resistance. Widener’s seals the deal with fast shipping! -
