The chambers of my Flues are 2 3/4. It also has fluid steel barrels. Ive been told that by the serial number, the gun was made with the longer chambers. Ive no way to verify this however. Never the less, it has been shot by the previous owner with factory RIO 2 3/4 7/8 ounce factory loads with no ill effects as of yet. I have measured the bore diameter, thickness, chamber length and choke diameters and all appear to be within tolerances.
If the chambers were lengthened from 2 1/2 to 2 3/4 is there any benefit to shooting the shorter shell in the longer chamber?
Again, I am well aware of the potential for disaster with shooting modern full power loads in vintage shotguns, hence my questions. I want to develop a reduced payload, low pressure load that patterns well and will allow me enjoy shooting this little gem.
Thanks again for all of the replies and the advice.
