We're trying to find a low decibel 20 gauge shot shell to be used at a summer camp. The "standard" loads are too noisy and the neighbors across the lake are complaining about the noise. We've made noise checks in winter and summer. It appears that the sound across the lake is only a nuisance during the summer months and there is no problem during the winter. We feel that the noise may be echoing off of the leaves. We seem to have 2 options, cut down a few acres of trees to increase the "buffer zone", or find a low db shotshell. Obviously we would prefer not cutting trees, so we're looking for a "quiet" shotshell. I've heard rumors that one exists, but don't know where to look. Any ideas would be helpfu.
