BACK IN STOCK! This is the 75 grain TAP® SBR cartridge in caliber 5.56 NATO.
Hornady Item No. 81295. Packaged 20 rounds per box, 10 individual boxes in each order. All have identical lot numbers.
2018 production. The new 5.56 TAP SBR meets FBI protocol through all six barriers and is the first load specifically designed for short-barreled rifles.
Specifically designed for short-barreled rifles, Hornady's new 5.56 NATO
75-grain TAP SBR bullet meets FBI protocol and is infused with
technology from Critical Duty FlexLock pistol bullets. The TAP SBR
utilizes a propellant developed specifically for optimal performance in
barrels size 10.5 inches 11.5 inches, and is effective in both
suppressed and unsuppressed rifles. Sound signature tests have shown
reductions of 6 to 7 decibels compared to other loads, according to the
company. In addition, the efficiency of the propellant results in a 15%
to 20% temperature reduction, delivering a progressive burn rate.
Range Report by Molon on Lightfighter.net
"Went to a Hornady demo on the terminal ballistics of the Critical Duty
and TAPS rounds, Seems the way they described this round is purpose
built for SBR so that all the powder burns in the space of the short
Barrel, You don't get the flash without a suppressor or the excessive
residue in full power load and buildup in suppressors. The build of the
round is to also meet FBI protocol. Says its best for 10.5 to 11.5 inch
- Specifically Designed and Optimized for short-barreled rifles (10.5"-11.5")
- Meets FBI protocol though all six barriers
- Proprietary propellant technology
- 6-7 db sound signature reduction suppressed
- Low Flash
- Exceeds FBI accuracy standards
- Muzzle velocity: 2321 fps out of 11.5" 5.56 NATO test barrel 1:7"
- Muzzle energy: 897 ft lbs
The TAP® SBR™ bullet uses the same heavy InterLock® technology used in Critical Duty® FlexLock® to mechanically lock the jacket and core together. In glass, the ogive portion of the bullet shears off at the InterLock® leaving a clean slug to achieve desired penetration.
While similar to the Critical Duty® FlexLock®, the 75 gr. SBR bullet does not use Flex Tip® Technology, but does have exposed lead to initiate expansion across all FBI barriers. In all barriers except for glass the bullet expands in a traditional manner creating very large and deep temporary wound cavities.
The FBI protocol for short barreled rifle testing differs from the FBI protocol of handgun testing with the addition of a 7th test. This test consists of shooting an additional round of ammunition into bare gelatin at a distance of 100 yards to determine how the ammunition performs at reduced velocities. TAP® SBR™ meets FBI protocol in each of the 7 stages of testing. TAP® SBR™ is designed to work specifically with velocities produced from 10.5-11.5” 5.56 NATO 1:7 twist short barreled rifles. TAP® SBR™ consistently provides 1.5” 5 - shot accuracy at 100 yards from 11.5” SBR’s.
TAP® SBR™ utilizes a proprietary propellant and the load is designed specifically for use in 10.5-11.5” short barreled rifles.
Many rifles chambered in 5.56 NATO are not realizing their full
potential when shooting 223 Rem ammo. To get all the
performance 5.56 NATO can deliver, you need a
5.56 NATO load. 5.56 NATO chambered rifles were designed to take advantage of the
higher pressure of the 5.56 NATO cartridge — higher pressure translates
to increased velocity, higher energy and harder-hitting performance.
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.
