Corbon is now making a new .223 Remington load called the Urban Response.  The new line of ammunition appears to only have one load…for now.  It is unknown at the time of this writing if additional loads are in the works.

The .223 load uses “Match Quality Lapua Brass” and Corbon claims the ammo consistently produces 1/2″ groups at 100 yards.  […]

MSRP is $63.75 for a box of 50.
