300 H&H

Showing all 2 results


  • The .300 H&H Magnum Cartridge was introduced by the British company Holland & Holland as the Super-Thirty in June, 1925. The case was belted like the .375 H&H Magnum, and is based on the same case, as also is the .244 H&H Magnum. The belt is for headspace as the cases’ shoulders have a narrow slope rather than an actual shoulder. More modern magnums continue this practice, but headspacing on the belt is not necessary with their more sharply angled shoulders. The cartridge was used by American shooter Ben Comfort to win the 1000-yard Wimbledon Cup Match at Camp Perry in 1935, and it was used again to win the international 1,000 yard competition in 1937. Winchester chambered the Model 70 in .300 Holland & Holland Magnum in 1937.

    The cartridge offered superior ballistics to the .30-06 for long range, and the .300 H&H is almost as versatile with all bullet weights and types, especially if well-developed handloads are used. It excels with the heaviest .30-calibre bullets in the 180–220-grain range.

    It has never been as popular as the .30-06; but the mystique of well-crafted rifles chambered for the .300 H&H keeps the cartridge in use despite its repeatedly reported demise. The .300 H&H is a fine African plains game cartridge, and suitable for all but the most dangerous big game.

    Choice Ammunition has taken our 100% hand-loading techniques and produce an extremely accurate, highly dependable round for the .300 H&H 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 180 grain Barnes Tipped Triple Shock (TTSX) round the best you can buy on the commercial market today.

    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.

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!
