question
If the end barrel (CZ_557 Sporter for ex.) is conical, who and how can interpret, the grind scale collimator when we do the zeroing impact point?
Depending on which caliber CZ 557 you have. As long as the arbor matches the caliber there is no problem. The barrel being conical would have no effect on the arbor of the matching caliber.
