I think ejectors are good on clays guns and if used in places where picking up your empties is not a problem, such as your own property if you don't mind the litter. On public land or on private land picking up empty hulls is just good conduct. One of the reason I prefer doubleguns to pumps or semis is the fact I need not pick up my empty shells 99% of the time. Leaving emtpties lying on the ground is the same as leaving aluminium drink cans, spent Bic lighters or cigarette butts. I can't see why ejectors would be needed on the trap range even for doubles? I can't say about sporting clay requirements or skeet for I have never shot either. Perhaps in those two games the birds come in greater numbers than two? I reload my shells and when hunting and using my 870 I pick up my hulls and feel uncomfortable when I can't find shells I have ejected. I use doubles almost exclusively now, except for a semi for trap (shell catcher attached). I have only one double with ejectors and I have removed the springs. I do not go to Argentina for doves so I have had few problems. I should tell you that I am an oddball and kind of like putting shells into and taking them out of my SXSs- don't know why I just do. Some probably enjoy seeing empties fly over their shoulder? As far as collecting goes- ejectors are more desirable.
