I have 3 v4’s 4-16x44 with the t-30 zmoa-i reticle on a 6.5cm, 6.8western, and a .300 Win. Mag. All of them have been good to me over the last 2 years. Have not had issues with environmental elements in the field. 2 are on tikkas in DNZ rings and one on a browning in Talley rings. Admittedly for tracking I have not gone beyond 300yds yet. I have been shooting once a week with the 6.8w for the last 2 months going from 100-200yds and back with no issues. More than happy to get together if you’d like to feel one out before you make a decision.
