Shooting spent shotgun shells with my new to me, .22 Webley Alecto using open sights. I see you've already had the pleasure though...

However, there's nothing like hitting something like a shotgun shell slightly hidden behind a spinner target, or layed flat like a 3/4 inch target and having them ping off in random directions, made me feel like a shooting god! I also made various reactive targets using fun snaps and paper caps concertina'd and sellotaped to old bits of hardboard.

Brilliant fun!!!
