Tubb 6mm Boron Nitride Coated D-TAC 115 Gr
Superior Shooting Systems LLC is pleased to introduce its NEW 115-grain 6mm RBT (Rebated Boattail).
This brand-new high-BC bullet is similar to previous DTAC bullets with respect to its overall form, but has incorporated a very important design change: it has a rebated boattail. During testing with an Oehler 88 at 1000 yards these bullets provided a measured G1 BC of .620!
A RBT obturates (conforms) faster and more efficiently to a rifle bore and results in quicker sealing and less gas blow-by. The result is significant increases in accurate barrel life compared to a diet of conventional boattails.
Additionally, the RBT design slows down carrel throat erosion. This erosion results from the "flame-cutting," effect of burning propellant gases, which is intensified by a conventional boattail design. Along with extending the accurate life of a new barrel, this also means that our 115 RBT will perform better in a rifle that's already suffering from throat erosion.
Fired from a 6XC cartridge, velocities easily surpass 3000 feet per second, with low recoil.
