I hunted their 10 years ago on a youth cow tag, and I remember hearing some bugling 1st rifle. Not really info to go on but that's my 49 experience. Hoping to draw there next year for archery, so I hope they are bugling then. Personally I wish they would stop moving the last day of archery season up. I haven't hunted rifle since that youth tag but it seems at least the last 2 years in south colorado it hasn't seemed like the rut had really got going by the end of archery season, so I'd expect 1st season has rut potential.
