Due to dismal sales over the past 4 years, the 440 CorBon is being dropped from the Tromix line up. The last two remaining uppers will be sold (On EE now) and that will be it.
The 440 CorBon was actually the very first caliber offered by Tromix back in 1999. Only about six (6) of them have ever been sold.
The 440 is a real sleeper in the big bore AR arena. It packs the same punch as the .454 Casull, yet has substantially less recoil then either the 458 SOCOM or 50AE. It will launch a 180gr bullet at 2300fps, 240's at 2050fps, and 300's at 1800fps.
All good things must come to an end...........
