（AAC）によって開発された中間弾薬。 7.62×35mmとも呼ばれる。標準のSTANAGマガジンに5.56mmNATO弾と同じ装弾数を確保した上で 7.62×39 mm弾や7.92×33 mm Kurz弾に近い威力を実現する高速弾と、サプレッサー使用時に高い静音性を実現する亜音速弾の二種をコンセプトとして開発された。 300 BLKの弾薬は7.62×40 mm Wilson tacticalに対応したチャンバーを装備した銃では使用できない。 [3], 5.56×45mm NATOは軍事の世界で広く受け入れられてきたが、一部の特殊部隊が遭遇する任務の性質上、高エネルギーかつ高弾速の弾薬よりも静音性に優れる亜音速弾薬が必要とされ、9mm弾とサプレッサー付きの銃器(多くはSMG)を装備する場合がある[4]。, この需要を満たすために、AACはRemington Defenseと協力して300 AACブラックアウトを開発した。この新しい銃弾は、大口径弾薬に劣るM4の特性を解決することを目的としていた。コルト・ファイヤアームズや他の武器メーカーも同様に以前からさまざまな新弾薬をARライフルやカービン銃向けに開発・製造していたが、様々な問題が発生した。特に7.62×39mmを使用するAR-15クローンなどは、特別に改造されたAK-47マガジンを使用しないと、マガジン内で弾丸が傾斜するため給弾不良が発生した。[要出典]また、弾薬の直径が5.56×45mm NATOより大きいため7.62×39mm専用に改造されたボルトを装備する必要もあった。6.8 SPCや6.5 Grendelなどの弾薬でも同様にボルト交換が必要だったが、標準のSTANAGマガジンを共用可能だった(ただし薬莢のサイズから、30発用マガジンでも25〜28発しか装填できない)[5]。, .300 Whisperシリーズなどのワイルドキャット弾はこれらの問題を解決したものの、単発拳銃で広く使われる物で、業界標準の銃弾寸法が欠如しており超音速と亜音速の規格双方で、ARタイプの銃への負荷が理想的ではなかった。また、これらの弾薬の多くは、M4カービンのチャンバーの圧力要件に適合しない粉末装薬を使用しており、STANAGマガジンへの装弾ができないように銃弾の全長が長くされていた。さらに、亜音速の弾薬をサプレッサーと組み合わせて運用すると、ベトナムでのM16の最初期のモデルで見られたものと同様に、ボルトのストロークが短くなり過度の汚れが顕著に発生した[6]。, 開発時にM4 / M16を主に使用する銃として念頭に置いたことで、設計者は、弾道要件を満たすだけでなく、銃自体への改造を最小限に抑え、バレルの交換だけで弾薬を使用できるように設計した[7]。, AACの研究開発ディレクターであるRobert Silversは、次のように述べている。「私たちは2009年に開発を始め、ほとんどの開発作業は2010年に行われました。ある軍の顧客は、通常のボルトやマガジンを使用しつつ、標準マガジンの装弾数30発のまま.30口径弾をM4プラットフォームから射撃可能にする方法を求めており、彼らは要求スペックに適合する弾薬の情報を望んでいました。RemingtonはSAAMIの会社であるため、.300-.221や.300 Whisperを使用することはできませんでした。そこで私たちは、.300-221からワイルドキャットの概念を取り去り、.300-221に対する最終仕様を決定し、SAAMIに提出しなければなりませんでした。そして私たちは策定した最終仕様の弾薬を.300 AACブラックアウト（.300 BLK）と呼ぶ事にしました。」[8], その後300 AAC Blackoutは、2011年1月17日にSAAMIによって規格として承認された。, 2011年10月23日、USAMU所属のSSGダニエルホーナーは300 AAC Blackoutを使用し第四回のUSPSA マルチガンナショナルチャンピオンシップで優勝した[9]。, 現在軍による大規模な採用はされていないが、特定の特殊作戦部隊が使用している。[要出典], 2015年7月、オランダ国防総省機関は、オランダ海上特殊作戦部隊（NL-MARSOF）向けに195丁の300 BLK対応チャンバーを装備したカービンへの入札を発表した。その目的は亜音速弾および無鉛フランジブル弾を購入することであり、.300 AACブラックアウトが正式に軍事採用された初の事例であった[10]。2016年12月、NL-MARSOFは、耐衝撃バイザーヘルメット用に開発された新型折りたたみ式ストックを装着した195丁のSIG MCXカービンを配備し、軍用で制式採用した初のユーザーとなった[11][12]。, 2017年7月14日、英国国防総省は5年間（オプションで5年間）での契約を締結し、.300ブラックアウトの超音速および亜音速弾の供給を開始した。すでに弾薬が使用されていたということも注目された[13]。, 2017年3月現在米国特殊作戦司令部（SOCOM）は、5.56から.300 AACまで対応するコンバージョンキットの提案を防衛業界に要求しており、より広い特殊作戦群へ向けて利用可能にしたいと関心を強調している。現在、.300 AACは、主にJSOC内、特定の特殊作戦部隊内で限定的に採用されている。, 125グレイン超音速カートリッジによる最大推定有効射程は460メートル(503ヤード)。 220グレイン亜音速カートリッジの有効射程は200メートル(219ヤード)[要出典]。, 300 AACブラックアウトは、 AR-15で7.62×39 mmと同様のエネルギーを達成しながら、標準のARマガジンを最大の装弾数で使用できるように設計されている。7.62×39 mm弾のテーパーはARマガジンにおける供給の信頼性を落とすと共に、ボルトに摩耗を引き起こした。14.5インチ (370 mm)M4 Carbineの14.5インチ(370mm)バレルから放たれたM855 5.56×45弾の有効射程は500メートル。弾丸はその距離でかなりの弾道降下と偏流をし、運動エネルギーを失う。それに対して16インチ (410 mm)バレルから放たれた125grain (8.1 g)300 BLKラウンドは、より初速が低く、より大きな弾丸の落下と偏流が発生する。しかし、M855が500メートルで持っているエネルギー量と同じエネルギーを700メートルの時点で.300ACCブラックアウトは保持している。命中確率の観点からは、.300ACCブラックアウトは460メートルの有効範囲を持っている。9インチ (230 mm)バレルから放たれた125 gr BLKラウンドはM4からM855と同じ銃口エネルギー、そして440メートルで5パーセント以上のエネルギーを持っている。7.62×39mmの銃弾と比較して、荷重を変えた300 BLKの砲弾は、同じ長さの砲身から弾道係数とエネルギーが向上している。Barnes TAC 110グレインのような300 BLKラウンドは、「バリアブラインド」性能を持ち、数インチの硬いターゲットを貫通することができる。.300 BLKを使用すると、ユーザーは1丁の銃で、亜音速、超音速、V-MAX弾、またはバリアブラインド弾のいずれかを弾倉を交換するだけで切り替えることができる。接近戦用にH&K MP5を交換することができ、マガジンを更新するだけで、M4カービンを凌駕して戦いをより長距離化することができる。[要出典].30口径の銃弾は、5.56×45mmの弾頭弾頭面積が89.1パーセント増加しているため、柔らかいターゲットに、より大きな創傷と永久空洞を残す。また、より深く貫通し、そして最初はより速く揺れる。300 BLKラウンドは4.5インチ (110 mm)の短いバレルから有効である。9×19mm MP5、5.7x28mmの FNのP90、4.6×30mm MP7のようなサブマシンガンと同等の軽さ、コンパクトさ、静粛性を持ちながら、より長いレンジでより高いエネルギーと精度を持つことができる[14][15]。, 5.56 NATOよりもストッピングパワーを高めた6.8×43 mm特殊用途弾と比較して、300ブラックアウトはさまざまな機能を備えている。300 BLKは、7.62×39 mmと同等以上のエネルギーを持ち、サプレッサーとの併用を前提に、特定の短距離にフォーカスして設計されている。初期の6.8 SPCは、5.56×45 mmよりも全範囲でより多くのエネルギーを持つように設計された。それは飛距離で性能を維持する高速の比較的小さな発射体を持っている。200ヤード (183 m)、300 BLKが2インチ (51 mm)滴それが30インチ (760 mm)落とす間、 6.8 SPCより低い500ヤード (457 m)より低い115grain (7.5 g)6.8ラウンドのマズルエネルギーは1,694フィート重量ポンド (2,297 J)そのより速い速度のため、125grain (8.1 g)300 BLKラウンドのマズルエネルギーは1,360フィート重量ポンド (1,840 J)両方の弾丸は、対応弾薬を換装されたAR-15で使用されるために作られた。6.8 SPCは時代遅れの.30 Remington弾を中心に設計されているため、換装がより困難である。別のボルトが必要になり、標準マガジン容量が減少する。300 BLKは換装を容易にする目的で作られたので標準的なボルトでも動作し、マガジンを通常の装弾数で使うことができ、必要なパーツの交換はバレルのみである[16]。, 300 BLKの非常に有利な点（一般的な.223 / 5.56口径との類似性）も、2つの弾薬が混在している場合は問題になる可能性がある。2つの弾薬はチャンバーの寸法がほぼ同一なため、SAAMIは.223(5.56×45)チャンバーで300 BLK弾を使用してしまう組み合わせを危険と見なしている[3]。300 BLKの弾頭は.223口径(5.56×45)よりも大きいため、誤って発射した場合弾頭とガスの行き場がなくなり過度の圧力がバレルと銃内部に発生しライフル自体が爆発し負傷や死に至る可能性がある。両弾薬は非常に混同しやすいため、両方の弾薬に対応した銃器の所有者は、銃とマガジンを明確にマーキングし、マガジンを装填する際は毎回目視で確認することによって、銃とそれぞれの弾薬を慎重に分けて管理することを勧めている[17]。300 BLK弾が実際に.223バレルに収まるかどうかは、弾丸の長さと形状、弾丸の圧入の深さ、ネックの圧着、および装薬の量によって異なる。理想的には、銃弾はより長い弾頭を使用し、薬莢に既定量の装薬を充填し、発射体を所定の位置にクリンプ加工する。, 300 AACブラックアウトは、SAAMIによって標準化された.300-221である。Hornadyは、300 AAC Blackoutを使用するライフルであれば300 AAC Blackoutスペック内で作られる.300 Whisper弾薬を撃つことができると主張している。これら2つの銃弾のリロードダイは、多くの場合同じである[8]。, American National Standard Voluntary Industry Performance Standards for Pressure and
