  • .338 Remington Ultra Magnum (RUM) 300 Grain Nosler AccuBond- The .338 Remington Ultra Magnum is a .338 caliber rifle cartridge introduced by Remington Arms in 2002. It is a beltless, rebated rim cartridge based on the .300 Remington Ultra Magnum case shortened .090″ and necked-up to accept a 0.338-inch (.338 caliber) bullet. The .338 Remington Ultra Magnum has a similar case capacity as the .338 Lapua Magnum and somewhat lower than that of the .338-378 Weatherby Magnum. It is one of the most powerful .338-caliber rounds in production.

    The .338 RUM is a well balanced cartridge ideal for hunting large bodied game at close to extended ranges. There is a great deal of interest in .338″ caliber cartridges for long range shooting as well. This is specifically due to high BC mass produced bullets available. While it takes a great deal of powder to push a 250gr to 300gr bullet at acceptable velocities for long range shooting, the performance has trumped the cost in the minds of many shooters (not to mention military and law enforcement world-wide). While 225 grain projectiles have become more popular in recent years, the 300 grain bullets are ideal for large animals such as elk, moose, and the big bears—if one can tolerate the recoil.

    Choice Ammunition has taken our 100% hand-loading techniques and produce an extremely accurate, highly dependable round for the 338 Remington Ultra Magnum in this load. Our loading tolerances are only matched by passionate hand-loaders in their own loading rooms. Consistent seating depths, powder charges and proprietary formulas of Choice Ammunition, make this 300 Grain Nosler AccuBond round the best you can buy on the commercial market today.

    The Bullet:

    Nosler’s AccuBond bonded core bullet. Through a proprietary bonding process that eliminates voids in the bullet core, AccuBond marries Nosler’s traditional copper-alloy jacket with its special lead-alloy core. The result is a bullet that flies true, penetrates deep, won’t cause extensive barrel fouling, and will retain 60-70% of its weight. The white polymer tip helps protect against deformation while initiating expansion upon impact.

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!
