I have had a SBE 1 for years. Originally for the foreshore , where it worked faultlessly. I am a great " barrel wiper", and all guns get wiped over with an oily rag when I have cleaned them. I've not had any rusting. The last four or five years, I have been using it for pigeon shooting exclusively, with Hull's "Super Fast Pigeon " cartridges. I was getting regular hang ups, and ordered a recoil spring ( to go in the stock )for a 2 3/4 " gun, and replaced the original one, which I have kept for the marsh . This is obviously my own modification, and may not be a good idea for others. But it has worked well for me.
