Thanks to everyone for the replies. Computer problems and work prevented me from posting earlier. Trigg Davis and I used the loads I did up when he and Richard Flanders came down to Debolt the last week of September. In hindsight I should have used a 16 ga card in the wad to fill it a little more. The shells were hard to fit in the chambers and extract. Live and learn. They worked fine on the geese and ducks we shot, especially for Trigg who was using my light 10. He was hitting almost everything he shot at. Unfortunately, I had to retire my 3 frame 10 after I put some cracks in the stock head the first morning. Three days after I returned home the temperature dropped and all the waterfowl vanished. Living on the northern edge of cultivated land the waterfowl season is best described as sudden and short. Bill, the MWT on my light 10 are 32 and 33 thou. Here's a few pictures of the old girl. After seeing the beautiful refinished barrels on Rich's Parker I'm thinking of sending these out to have them redone.
30" barrels, 2 7/8" chambers, and mirror bores. She's marked J.L. Rawbone, Toronto, Canada, but obviously started out at Westley Richards. A great handling British gun, lighter than several of my 2 frame 12s. Richard, thanks for the offer to buy some of those BBs you bought, and thanks again for leaving me some of your hand loads and shell boxes. I used them to adjust my Mec so any I load now shouldn't give the same chambering problems. It will be a while before I need any more non tox, we'll talk about it in the new year. I've also have that 1880, 10 ga, grade 2 lifter I mentioned on the way to me now, not sure of the chamber length. Hopefully it will make it into the blinds with us next year.
