Chamber reducers are the salvation of ten gauge owners. Little Skeeters are about the only ones still available, but I ordered a set of 10-12 last week and have them in hand now. I was just testing the water to see if they were actually still in business. I have some "in stock" but ordered more. I use reducers in all my eights and tens as well as loading real 8 and 10 gauge shells. I grind an area of the rim away on the reducer so I can remove the 12 gauge shell with my fingernail without ejecting the entire reducer.
