I just acquired a .32 caliber barrel and breech with bolt to go on top of a discovery tube. Measuring the barrel, it is .500" OD. the barrel bore in the breech measures .509 ID. If I tighten setscrews to hold the barrel in as it is, the barrel will be squeezed out of round. There is not room to bore and sleeve the breech. I'm thinking some .003 or .004 ss shim stock around the barrel stopping just short of the transfer port. I'd like to use brass because it's more flexible, but I think it might cause corrosion.
What say you?? Any ideas will be appreciated.
