Having looked at lots of options and tried many out I have finally had a go at putting plumbers mait in my target pellet catcher. What I'm after is a silent pellet catcher as I shoot in the house at 6m with a pistol - I'm shooting lots at the moment to try and get somewhere near where I was 30 years ago - almost hopeless it seems, or do I think I was better than I really was.
It seems to work well but I do hope it does not slowly gloop and fall out but what a mess it was getting it from the tubs and into the catcher.
