I don't shoot golf courses myself, and I shoot a lot less than some other members. When I do shoot I always strive to pick up empty cases - shotgun or rifle, and I guess a lot of shooters would do the same.
I have seen lots of rimfires clips where the empty case are just ejected from a bolt rifle and left, but watching a clip on a golf course using a 10/22 Ruger surprised me.
Surely even little .22 cases strewn about would really upset golfers and green keepers ?
Not criticising, just an observation.
