I'm trying to get into your pocket a little bit, but about the handiest device around for lots of shots from a shotgun is a shot flask (or snake) with an Irish head. No fiddling and no fuss, and darned little if any spilled shot.
This is an example of what I'm talking about. You can save lots of money by buying the Irish head yourself and making one, or slap cash and buy one already made. Either way, it will sure come in handy on hunts with a fair bit of shooting.
Not mandadtory by any means, but high on the "nice to have" list.
