Just picked up a new Nitrex TR Two 3-15x50mm with the EBX reticle. It comes with a ballistic chart but the round I'm shooting is not listed (257 WBY) The directions also do not tell you what power to set the scope at when using the EBX reticle, does changing the magnification affect the the distance the stadia lines are graduated for? Like when you change the power on a Nikon it affects the distances the stadia lines are graduated for, IE at (200yrd zero) 3x the second stadia line is 502yrds at 9x the same second stadia line is 319yrds. Was wondering if anyone has been using the Nitrex/Weaver scopes is familiar with the EBX reticle as to how exactly its calibrated...... Thanks!
