As the 6.5 trend accelerated, various companies brought out target bullets with even higher ballistic coefficients, due to elongated boattails and ogives. Some proved a little too long for the .260 in the standard short magazine length of 2.8 inches.

Berger Hybrid bullets get their name from the characteristics they pull from both secant and tangent ogives. Secant ogives (or the really pointy noses) cut through the wind, shoot very flat and resist the effects of wind well.
