Transcription

1 55 gr. TAP URBAN #83276 Polymer Tipped Spitzer Flat Base Bullet B.C. =.255 The Hornady 223 Rem 55 gr. TAP Urban is the preferred choice for use in SBRs, carbines, and rifles when the possibility for barrier penetration is low. Rapid expansion provides dramatic wound cavities and prevents over penetration on non-barrier engagements. These factors make this bullet a great choice when collateral risk is high. 55 gr. GMX TAP BARRIER #83295 Copper Alloy Flat Base Bullet B.C. =.245 TAP Barrier turns cover into concealment. Constructed of copper alloy, the 55 gr. GMX is a highly accurate solution for departments that are seeking a precise alternative to traditional bullets loaded in the 223. With its monolithic construction, the GMX boasts dependable terminal performance and high weight retention when encountering barriers. 60 gr. TAP URBAN #83286 Polymer Tipped Spitzer Flat Base Bullet B.C. =.265 The Hornady 223 Rem 60 gr. TAP Urban offers high velocity and performance similar to that of other polymer tipped Hornady 223 bullets. The 60 gr. bullet offers similar retained weight and penetration to the 55 gr. TAP Urban, and is the heaviest weight acceptable for 1-12" twist weapons. The heavier 60 gr bullet transfers more energy to the target for enhanced terminal performance. 62 gr. TAP BARRIER #83285 Spire Point Heavy Jacketed Bullet B.C. =.264 TAP Barrier turns cover into concealment. Hornady originally developed this ammunition to meet the requirement for a high-speed, barrier penetrating bullet that could be used for nuclear power plant security. The design of the TAP Barrier round allows the projectile to maintain its structural integrity while punching through barriers, yet still initiate expansion in soft tissue. For patrol carbine programs or any tactical situation where the need is for accuracy, barrier penetration, and terminal soft tissue performance, Hornady TAP Barrier ammunition is the ideal choice. 75 gr. BTHP TAP #80265 Boat Tail Hollow Point Bullet B.C. =.395 This match accurate load is our heaviest TAP offering in 223 Rem. The 75 gr. bullet offers deeper penetration than the 55 and 60 gr. TAP Urban bullets yet still penetrates less than most law enforcement pistol bullets. This bullet penetrates barriers with minimal deflection and breakup thus delivering more energy to the target. Whether fired through a barrier or not, this bullet generates very large and consistent wound cavities, serving as an ideal choice for 223 Rem sniper applications Remington Hornady Product Summary Hornady 223 Rem TAP loads are a unique offering to law enforcement professionals that combine reliable functioning with consistent performance, low muzzle signature, and exceptional accuracy in cannelured and crimped 55, 60 and 62 gr. bullets, and a 75 gr. load offering match accuracy. This ammunition features clean burning propellants and enhanced terminal performance, with rapid expansion and bullet fragmentation. These highly effective bullets will penetrate soft body armor making them an excellent choice for patrol rifle programs and SWAT teams. This line of ammunition is intended for Law Enforcement sales ONLY. B.C. = Ballistic Coefficient TAP APPLICATION GUIDE 51

23 223 REM vs 5.56 NATO 5.56 NATO vs.223 Remington In development of the 223 Remington as a sporting cartridge, Remington slightly modified the 5.56 NATO to improve accuracy for the varmint bullets popular during that era. The freebore of the 5.56 NATO chamber is approximately.130" longer than the 223 Remington, allowing more "jump" to the rifling lands. The maximum chamber pressure for the 5.56 NATO is approximately 3,000 psi higher than the 223 Remington. Combined, these characteristics allow for higher propellant charges; greatly increasing velocity for superior downrange performance. Firing 223 Remington ammunition in a 5.56 NATO chamber creates a reduction in pressure, sacrificing velocity. Firing 5.56 NATO ammunition in 223 Remington chambers will produce a dramatic rise in pressure which increases stress on the weapon, risking wear, permanent damage and/or injury. # Item 223 Rem 5.56 NATO Difference A Shank B Base Diameter C Shoulder Diameter D Neck E Neck-2/Case Mouth F Lead Diameter H Base-to-Case Mouth I Base-to-Shoulder J Neck Length K Freebore Length L Shoulder Angle (Degrees) M Throat Angle (Degrees) The dimensions above are from Pacific Tool and SAAMI. Dimensions in inches unless noted. The main differences between the two are the freebore length, lead diameter and throat angle. TAP APPLICATION GUIDE 73
