Yeah I did years ago. I used live ones, dead ones, dehydrated/dried ones.... and they were all rubbish. Imo the carp get on the (natural) snails simply because it's the easiest food source to harvest at the time. They're tuned into the food sources available in their watercourse and I don't think you can compete with that with any snails apart from those that are plucked out of the venue - so @jh92 has the right idea. Even then, there are other natural baits (maggots and worms) that will do a much better job of competing.
The snail discussion comes up every few years. Lots of guys try it. Hardly anyone has any real success. Imho, snails are just not a great bait.
