I am chambering a .300 win mag. It is my second chamber that I have ever cut, and the first with my current set up and lathe.
i am satisfied that my bore is running true, having used both a range rod and Gordy Gritters style of rod.
My set up is follows:
Manson Floating Reamer holder.
Micrometer stop.
Live piloted Manson reamer, with nice fitting bushing.
I know the tailstock is not perfectly aligned, but neither has the floating reamer holder reached it's extreme.
My problem is I have cut the chamber about halfway, I inserted both a dummy round and a fired casing into the chamber (after thorough cleaning) and found that the cases do not sit tight in the chamber, though the case mouth has bottomed out. It seems as though the chamber diameter is too big for the given length.
Any informed advice would be appreciated.
