6mm 115 grain DTAC Bullets by David Tubb
These are 6mm Rebated boat tail bullets.
Designed by David Tubb, perhaps the most winningest competitive shooter alive.
These are uncoated, pointed (closed tip) and sold in a 500 count box.
This brand-new high-BC 6mm bullet is similar to previous DTAC bullets with respect to its overall form.
During testing with an Oehler 88 at 1000 yards these bullets provided a measured G1 BC of .620!
A rebated boattail bullet obturates (conforms) faster and more efficiently to the rifle bore. This results in quicker sealing and less gas blow-by. The result is a significant increase in accurate barrel life compared to diet of conventional boattails.
Specifically, the RBT design slows down barrel 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.
From my personal experience, they function great in 6mm Dasher, and I get long barrel life and speeds similar to running 105 Berger bullets, with a much improved BC of the 105’s.
