Year end and year out Blacktail bucks start running around like dummies on the 25th of october (typically the young ones) And then really kick off hard on october 31st through november 11th or 12th and then start winding down to the 20th. In certain areas theyll hit a second rut around thanksgiving but that will only happen in small pockets where does that havent been bred come into a second estrous.
That has been my experience in gmus 652, 654, and 667.
