Hey you made it up-side-down!
Oh wait, that is just the photo!
Looks real fine for a first "Shot". The 7mm is a bit of a different fit at the nib than others available. Good look overall though. Also, if you don't mind me adding, the joint at the casing and antler looks just a little skewed. This can be fixed even still, by placing the top barrel back on the mandrel (Pop out the finial stud). Use a sharp skew on an angle and taper the end just a hair toward the center (Toward the tube). It will smooth out that edge, and make the joint look sharp and tight. Thanks for sharing.
