I do convergent at like 200 or greater. That keeps you within a couple inches of your day optic to 400, by which point PID and ballistic drop makes it decreasingly likely that I’m squeezing a round off, and increasingly likely that this is a job for a clipon or comms. People worry about convergence too much. As long as you avoid full divergence, or too close of convergence, the results on target are indistinguishable from parallel, and within the expected limits of practical precision at night with a GP fighting carbine.
