The 2 fb groups I looked at were updated 1/25/2019 and 6/17/2016. Their website shows meets on the 3rd Saturday of every month, that's this weekend.
Mississippi River Rangers fb groups shows the same entries. Shows meets every 3rd Sunday, 4th and 5th Saturdays.
I'll be out of town or I would go the the range in Byhalia to see what's happening. Might try later in the month.
