Viper HD 3-15x44 Dead-Hold BDC

[Jholm]

I recently purchased a bergara ridge carbon in 7mm prc. I was looking at a Vortex Viper HD with the BDC. I plan to try out the Hornady Precision Hunter ammo 175 ELDX first, if that doesn't group well the Federal Terminal Accent. Does anyone have experience with the BDC retical and the 7mm PRC? I don't see the ammo as an option on Vortex site for the factory ammo bdc charts. Was looking for a yardage chart.
