I went there today with a friend and while I had done this in the past I got in trouble for it today as I either did not know they changed the policy or they didnt care in the past.
I was on the floor prone sighting in my .308 and I had just got done with my 5 rounds and the guy came in yelling no prone shooting and then walked out.
My answer to this then is put in nicer benches as the current ones are junk. Make they adjustable in height and out of nicer material. It is hard to sight in when the bench is way to tall if you are sitting in those folding chairs.
Thats Funny , I was with the group of guys to the right of you shooting the machine gun. I saw them get onto someone about that a few weeks ago and I was going to say something to you but since you were on the end I didn't think they could even see you doing it. Plus its not my place to make people aware of there range rules if they are not endagering myself or anyone else.
