This review explores a Glock 21 modified to fire the powerful .400 Corbon (or .40 Super) cartridge. The .400 Corbon is highlighted for exceeding 10mm power and its bottleneck design, which enhances feeding reliability. The setup features a ported, extended barrel for maximum performance, though the speaker laments the round's lack of popularity.
This video tests the performance of Cor Bon 9mm +P self-defense ammunition. Utilizing a Taurus GX4 and a P80 pistol, the test involves shooting the ammo through heavy clothing into ballistic gel to assess its effectiveness. The title "Can This OLD Dog Still Do Some Tricks?" suggests a focus on whether older ammunition or a less common platform can still perform well in modern self-defense scenarios. The description also includes channel membership information and disclaimers regarding safe shooting practices and the non-sale of firearms or ammunition.
This video features a gel test of COR-BON's 77gr MPR (TMK) ammunition in .223 Remington. The test, even from a short 10.5" barrel, demonstrates solid performance with significant penetration (14.5"), a retained weight of 37.2gr, and maximum expansion to 0.495". The description confirms the use of the Sierra 77gr Tipped Match King bullet and highlights the ammunition's marketed suitability for match, hunting, and home defense.
The .300 Blackout cartridge is best suited for specific roles like hunting or suppressed Short Barreled Rifles (SBRs) due to its optimized performance in shorter barrels. While it offers easy conversion from 5.56 NATO platforms and retains energy well at moderate distances (600+ yards), its high ammunition cost and potential reliability issues with certain gas systems are significant drawbacks. It is not recommended as a general-purpose 'plinker' round.
This review showcases an exclusive custom 10mm Hi-Point pistol conversion, demonstrating its reliability with hot loads and a straight blowback action. Testing included steel targets, water bucket terminal performance, and a ballistics gel test showing 10 inches of penetration and full expansion with Cor-Bon 135gr Powerball. The modification requires significant experimentation and is not a simple drop-in.
