(7,2 g) TAP SBR® NO. 80785 | Application: Entry, Patrol | Meets FBI Protocol* The Hornady® 7.62x39 111 gr. (7,2 g) TAP SBR® was specifically designed to meet FBI protocol and maximize performance in rifles and pistols with barrel lengths from 9" to 16" (229 to 406 mm) and twist rates of 1:9.45" (1:240 mm) The newly designed 111 gr. (7,2 g) TAP SBR® features a lead-free monolithic bullet with a large internal cavity and an elongated elastomer tip. This combination allows for expansion at velocities below 366 m/s, which equates to an expansion distance that is 3 times longer than that of a traditional 5.56 SBR with a 10.5" – 12.5" (267 – 318 mm) barrel. BARE GELATIN Bullet: 111 gr. (7,2 g) TAP SBR® BC: 0,140 SD: 0,152 Muzzle Velocity: 617 m/s Barrel: 279 mm Firearm: CZ Bren Twist Rate: 1:240 mm or faster Total Penetration: 432 mm Max. Cavity: 99 mm Depth to Max. Cav.: 102 mm Entry: 0,0 mm Retained Weight: 7,1 g Hornady® 7.62x39 is specifically developed for agencies that demand reliable terminal performance of the 7.62x39 over legacy FMJ options. The polymer tip initiates expansion upon contact, allowing consistent expansion and penetration through the FBI protocol, making it the optimum choice for the most demanding Units around the world. 7.62X39 255 GR. (16,5 g) TAP® SUBSONIC NO. 80795 Application: Entry, Patrol Hornady® 7.62x39mm features a 255 gr. (16,5 g) SUB-X (Subsonic eXpanding) bullet with patented Flex Tip® technology, specifically designed to expand at subsonic velocities. This cartridge is loaded with a powder that is optimized to provide flash suppression, clean burning, yet function in short barrel to carbine length rifles. BARE GELATIN Bullet: 255 gr.
