I think it is appropriate for you to ask him to adjust position.
My Sig pitches shells with great enthusiasm. Our range is outdoors and there is just a support pillar between each shooter. I line up so I'm beside the pillar. The shells fling out, hit the pillar, and roll to the ground somewhere around me.
A couple of friends and I were out shooting and on that day the range was completely full. I happened to be the only woman there...
One of my shells hit the pillar and went straight down my shirt becoming lodged between my bra and my hooter. And oh boy was it HOT HOT HOT!!!
Man I'll tell you what, a red-headed woman jumping up and down with a loaded gun and a hot shell on her hooter can flat clear out a public firing range...
