EBR 12 Gauge Frangible Entry Slug 435gr 12 Gauge 435gr MAX Expander Slug

Engel Ballistic Research is proud to introduce our 12 Gauge Expanding Slug for home defense and hunting applications. This slug will expand out to 1.4325" on impact with soft tissue. The maximum expansion of this devastating round allows for an extreme transfer of energy. Please watch our ballistic gel test video for a demonstration of this energy transfer.

MSRP: $24.75
EBR 9mm MAX Expander 124gr 9mm 124gr MAX Expander

Our 9mm Expanding ammunition maximizes lethality, while still penetrating 12" on average during an FBI Ballistic Gel Test.

MSRP: $29.00
EBR .45 ACP MAX Expander 185gr .45 ACP 185gr MAX Expander

Our .45 ACP MAX solid copper expanding ammunition maximizes lethality and cavitation, while not over penetrating making it ideal for home defense and law enforcement scenarios.

MSRP: $34.80
EBR .223 Max Expander 62gr Ammunition .223 REM 62gr MAX Expander

The Engel Ballistic Research .223 Solid Copper Expanding ammunition allows for the ultimate expansions of 0.77" on impact with soft tissue. This translates to more lethality when you need it. The round is MOA accurate out of a quality weapon platform.

MSRP: $39.00
EBR .300 Blackout MAX Expander 125gr Ammunition .300 Blackout 125gr MAX Expander

The Engel Ballistic Research .300 Blackout HVE (High-Velocity Expander) expands to an astonishing 0.88" on impact with soft tissue making it the ideal hunting or home defense round. The round is MOA accurate out of a quality weapons platform.

MSRP: $41.00
.300 Blackout 200gr Subsonic MAX Expander .300 Blackout 200gr Subsonic MAX Expander

This ammunition revolutionizes subsonic hunting in the .300 AAC Blackout caliber. In the past, the terminal ballistics of subsonic ammunition, including the .300 Blackout, have been limited in respect to knock down power and wound channel size by projectiles which did not expand. Engel Ballistic Research’s new .300 Blackout "Phantom" Subsonic Expander maximizes the transfer of energy on live targets exponentially by utilizing a projectile which dramatically and rapidly expands on impact with soft tissue creating a large cavitation while at the same time cutting through live tissue in a way similar to a broad head on an arrow.

MSRP: $43.00
EBR 7.62x39mm Subsonic Max Expander 220gr 7.62x39mm 220gr Subsonic MAX Expander

This ammunition revolutionizes subsonic hunting in the 7.62 x 39mm caliber. In the past, the terminal ballistics of subsonic ammunition, including the 7.62 x 39mm, have been limited in respect to knock down power and wound channel size by projectiles which did not expand. Engel Ballistic Research’s new 7.62 x 39mm "Ghost" Subsonic Expander maximizes the transfer of energy on live targets exponentially by utilizing a projectile which dramatically and rapidly expands on impact with soft tissue creating a large cavitation while at the same time cutting through live tissue in a way similar to a broad head on an arrow.

MSRP: $43.00
EBR .308 Winchester MAX Expander 130gr .308 WIN 130gr MAX Expander

This high performance 130 grain solid copper .308 Win cartridge is built entirely from premium, match-grade components and is manufactured to strict tolerances.  It provides excellent (MOA) accuracy while maximizing projectile expansion and energy transfer for optimal terminal ballistics.

MSRP: $43.00
.308 WIN 175gr Subsonic MAX Expander .308 WIN 175gr Subsonic MAX Expander

This ammunition revolutionizes subsonic hunting in the .308 Winchester caliber.  In the past, the terminal ballistics of subsonic ammunition, including the .308 WIN, have been limited in respect to knockdown power and wound channel size by projectiles which did not expand.  Engel Ballistic Research’s .308 Winchester Subsonic MAX Expander maximizes the transfer of energy on live targets exponentially by utilizing a projectile which dramatically and rapidly expands on impact with soft tissue creating large cavitation while at the same time cutting through live tissue in a way similar to a broadhead on an arrow.

MSRP: $46.00
.300 WM 175gr Subsonic MAX Expander .300 WM 175gr Subsonic MAX Expander

This ammunition revolutionizes subsonic hunting in the .300 Winchester Magnum caliber. In the past, the terminal ballistics of subsonic ammunition, including the .300 WIN MAG, have been limited in respect to knock down power and wound channel size by projectiles which did not expand. Engel Ballistic Research’s new .300 Winchester Magnum "Max" Subsonic Expander maximizes the transfer of energy on live targets exponentially by utilizing a projectile which dramatically and rapidly expands on impact with soft tissue creating a large cavitation while at the same time cutting through live tissue in a way similar to a broad head on an arrow.

MSRP: $59.00
EBR .300 Win Mag MAX Expander 168gr Ammunition .300 WM 168gr MAX Expander

This high performance 168 grain solid copper .300 Winchester Magnum cartridge is built entirely from premium, match-grade components and is manufactured to strict tolerances. It provides excellent (MOA) accuracy while maximizing projectile expansion and energy transfer for optimal terminal ballistics.
