is this a good starter slingshot?

Nope. 50 years ago? Maybe. But if you are going to get into a sling shot these days, it's almost a waste of time to start with something that doesn't have a wrist brace, like this:

These allow you to get to something more like a full "draw" on the elastic, get more power out of the slingshot and help with stabilizing your wrist so you can get a consistent anchor on your face, and draw length for consistent flight.

I've killed dozens of cans, cups, starlings, and about anything else growing up with one of these.

Another great Hunting question....What caliber is it, Sport ?

look up in the tree . make your own sling shot .
