Shiner Bock -- the longer dry time is the problem I've had with similar forages when cut for hay (Haygrazer, Sudan, etc). But they sure do grow awfully fast under the right conditions and the cows love the hay. A crimper probably saves you a day. I know from experience how really disheartening it can be to watch the bermuda guys cut one day and bale the next, while waiting for my Haygrazer, etc. to dry --- especially when you get in one of the periods of frequent summer showers. Not to mention that the hay meadow takes much longer to dry out if you get a rain on the standing forage, as compared to bermuda.
Like DR Cattle, I have also had good dove hunts over that type of hay field. You might consider leaving some strips of millet, Haygrazer, etc. to head out in late summer and then shred them a few days before dove season starts.
