That's how I did mine. I single load so I filled the mag well of my choate stock with jb weld and when it was a putty like consistency, I took a really long OAL dummy round coated in sizing wax and formed a feed ramp that perfectly feeds into the chamber without any bullet contact. The jb adds weight and dries out pretty smooth. Nice cheap way to do it in my opinion. Rosco on this forum can hook you up with an xcaliber barrel. If you are going to throw 140gr, consider going for the 260 match chamber as it has more free bore so you can seat them out long and take advantage of the longer action. Alternatively, you can have A Smith ream the throat deeper. Snug the barrel nut and Robert's your father's brother.
