I have a few questions about some Nitro Specials I have acquired. I have a 12,16 and a 20. I have the 16 figured out what shell to shoot and all that. The 12ga I have looked at several differnt posts on the net and I'm still not sure. The 16 and 20 are marked 2 3/4 they are a 1937 and 1940 model. The 12ga is a 1923 model and is not marked for shell length. Here and there on the web I find info that (all 12ga Nitros were 2 3/4 from Ithaca) but some threads say they were I believe if memory serves 2 9/16 or 2 1/2. Does anyone know for sure? I assume a field load of 1oz or 1 1/8 oz of shot running about 1200 or 1250 should be safe to shoot in this gun? Would the 20ga be safe using a field load of 7/8 shot running 1200fps to 1250fps or should I find something a little lighter. All three guns are in perfect shape. Thanks for the help. Michael
