I had some nuggets that I knew were fresh in my tackle box, but only a few so I threw them away, well out my bedroom window. It has since rained, had storms etcs, but the sad remains of a few of the nuggets are still stuck on the lead flashing.
i have doubted that all of them dissolve properly, and in fact I think that some baits have been zig rigged without anglers realising it. After casting in when using them, I was only ever happy if I could see the nugget come to the surface after breaking away from the hook. The ducks on the lake would then be picking up the mush,
