Had this happen at the range today. The wife and I went to the local pistol range today to try out her new sig 9mm, I took my .40 m&p and we took both hers and my Walther .22s. We had about 200 9's, 200 40's and a 325 pack of .22s sitting on the bench next to our gear bag. This older gentleman which I have bumped into on occasion there walks up and starts picking up my wife's and my brass, I look at him and say "I'm saving my brass, so leave the 9's and 40s lay". He says "okay I'll leave yours" and starts picking up everything in sight, including mine. I then said to him, while pointing at our empties "these are ours" you can pickup everything back there" pointing behind the bench. I reloaded the guns, stepped up to the line we were shooting from, got a sight picture and there off to my 2:00 position is the guy bent over picking brass not more than 10 feet away. I got upset at this time as now it's a safety issue as he's in front of the line of fire. I say "okay, I've had it, get your azz back behind the bench". The guy looks at me and says "I'm okay over here". I return with" You're not here shooting, get out of here, until we're done shooting or we'll report you to the game commission for harassing us". (range is state range) He "f-bombed me, (my wife is still standing with me), called me an a-hole, told me to kiss his "rear end" and then walked back to the parking lot and stood there staring at us. I was upset, told the wife that I had had it and we packed up to leave and he returned while we were picking up the empties, I just said the heck with it and walked away, while calling him a bad name. I feel bad about this as he is a old guy who is just trying to make a few bucks to help his SS. but I really feel that he should have not been in a position to interact with me in the first place. Should range pickers be at the range while it's being used or should there or is there a rule that says they have to wait until the range is empty? Or am I just being a moron about this?
