  • .280 Ackley Improved 160 Grain Nosler AccuBond– The primary difference between the standard .280 Rem. and the .280 Ackley Improved is the steeper 40 degree, which lengthens the case body and allows for about 5 percent more powder capacity. When P.O. Ackley gave the .280 Remington a steep 40-degree shoulder and straightened out most of the cartridge case’s body taper, he likely knew he was on to something special. However, it’s doubtful he anticipated that more than a half-century later, his .280 Ackley Improved cartridge would blossom into a favorite of savvy open-country hunters across the West.

    Decades ahead of his time in cartridge design, Ackley became a household name for his work, at least among cartridge enthusiasts. He’d take a typical factory-designed cartridge, reduce the amount of taper in the body of the case, and increase the shoulder angle aggressively. These modifications resulted in added capacity, which increased velocity, and less case stretch, which resulted in longer case life. The .280 AI’s additional case capacity does good things, but it doesn’t change laws of physics. With equal barrel lengths, the Ackley Improved version gets you about 100 additional fps of velocity with a 140-grain bullet and a 24-inch barrel.

    Choice Ammunition, and our 100% Hand-Loading techniques- produce a round of ammunition for the .280 Ackley Improved that is demanded in big game hunting. Accuracy, consistency and dependability are crucial at that final moments of your hunt. Choice Ammunition takes this responsibility seriously by meticulously weighing each powder charge with our proprietary formulas and temperature insensitive powders, seating the bullet at the exact length for optimal performance and test firing each and every lot of ammunition at an average of 500% over industry average. We have no high speed production machines- only passionate and dedicated load technicians pulling each and every handle, producing one round of ammunition at a time. 

    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.

    The Bullet-

    Image result for eld-x bullets

    The Heat Shield tip of the Hornady ELD-X bullet defies the effects of aerodynamic heating and retains its shape to provide a perfect meplat (tip) that is always the same shape. A streamlined secant ogive with optimum boattail design, plus the highly concentric AMP bullet jackets, combined with the patent pending Heat Shield tip creates a supremely accurate, high BC match bullet. ELD-Match bullet BCs are measured with Doppler radar and corrected to standard atmospheric conditions. With high velocity, 0-400 yard impact, the bullet continually expands throughout its penetration path. The thick shank of the jacket and high Interlock ring keep the core and jacket together providing 50-60% weight retention. Upon low velocity, 400+ yard impacts, the Heat Shield tip drives backward into the bullet to initiate expansion. Exhibiting conventional expansion with a large mushroom and 85-90% retained weight the bullet provides deep penetration and large wound cavities.

Thank you for visiting Choice Ammunition!Home of Premium Ammunition- 100% Hand-Loaded in Western Montana.

As you may know, the ammunition and firearms industry is experiencing unprecedented times beginning with COVID 19 coming from China in early 2020. Some talked of defunding police departments about the same time, even as riots and lawlessness raged on in our cities with unrest. We then saw a very contentious presidential campaign and ultimately- an inauguration of what could be a very unfriendly 2nd Amendment administration controlling both houses of Congress. For these reasons and more, we see demand at all time highs in the industry, in addition to mass shortages of components. I personally do not see things changing any time soon either...

With this, we are doing everything possible to hand-load and get products shipped in a timely manner, but we cannot simply turn machines up like others! Any back-orders on this website that we allow, we feel will ship in a reasonable period of time and we are averaging about 2-3 weeks presently. However, we are reliant on our suppliers to deliver components to us also, and that can unexpectedly be delayed on occasion. When this happens, it is possible to see 30-60 days, and sometimes more- to get ammunition sent out to you. Please know, all backorders will be filled at the price you purchased the ammunition for. If you find something elsewhere- we are happy to cancel any order.

We try to answer all office calls and prefer calls over emails or social media. We ask you to please refrain from calling or changing your order unless it is absolutely necessary- keeping in mind the time-frames I mentioned above. Every call we answer removes the focus on sourcing components and loading/shipping your ammunition!  We promise to get your order out as soon as we possibly can- yet, ask that you please understand this crazy market we are all in- if indeed you are delayed!

We do not believe in price gouging or increasing margins in a market such as this- and we will do everything possible to remain competitive with “factory” ammo, while providing our premium hand-loaded ammunition to the market. It does appear that prices may increase this year however, as there is much volatility in pricing for our brass, bullets, powder and primers.

Thank you for considering Choice Ammunition if you are a new customer- and thank you for another order if you are returning. We truly appreciate all of you and have built our business from going the extra mile with our products and for our customers!
