Myself and two buddies were at the local club today. We had 2 ruger 44mag redhawks, 1 44mag super redhawk, 2 smith and wesson 9mm's, 1 ruger 9mm and a browning 22 semi pistal. Had the whole place to ourself, 2 guys came when we were cleaning up.
We were not at a GC range. We were at a local Gun Club we are members of. As far as I know it is legal to shoot semi auto hadguns and rifles a GC ranges a well, as long as you have a hunting liseance or range permit.
I was at the range on GL42 and saw a deputy write up 3 guys for using semi's to shoot. Perhaps it was because of rounds loaded but if memory is correct they paid $187.50 each. I may be totally wrong, has happened in the past, but when I shoot my semis I go to private ranges.
