Thanks Steve.
That was what concerned me. At .441 chamber that is not a lot of case expansion for a rifle in hot conditions.
I cant imagine what that reamer was meant for. It would be ok for me as I could OS turn the cases a couple of thou, but I wouldent want to sell the rifle on like that in case it was passed on to somebody that dident know.
Somebody must have wanted to build a 416 Taylor BR sometime. :-)

Thanks again for taking the trouble.

Mark
