This is the response I received to my email:
Beginning on April 1st it will be mandated that the rifle range at Winamac FWA shall be manned with a range officer during all hours of operation. Unfortunately we do not have the personnel to man the range for the amount of days and hours that we were open prior to April 1[SUP]st[/SUP] of this year. Due to this mandate the range hours and days of operation will need to be decreased.
The separate muzzle loading tables were put in place for safety reasons to keep muzzle loading powder away from the shooting benches where accidental ignition could possibly occur.
Thanks for the information. Sounds similar to what the Winamac FWA told me on the phone today. Well...I guess it will be what it will be. The state will do as they see fit. I guess if one does not like the changes, one can always join a pay per year private range.
