If you verify at the range before hunting, any quality optic is not going to magically stop tracking during the hunt but All scopes can and will fail given the right circumstances. ALL scopes can and will fail given the right impact. NF, S&B, Leupy... doesn’t matter. Just like all optic manufacturers will have some QC issues. Shoot there are parallex issues with some Tangent Thetas.
Yup, but the point is why choose one that is more prone to failure?
