Recently talked to Ed about getting a 10" .17HMR barrel.  He recommended buying a 14" T/C then cut and target recrown.  He quoted me barrel cost + $40 to do the cut and recrown by his gunsmith associate.  Knocked a few bucks off if you don't  need sights as well.  
I am brand new to the game, so far have a 10" .44Mag and Match 22LR.   Didn't think I wanted anything over 10" but now I'm leaning towards going with the full 14" .17HMR.  I'll wait and have Ed cut me a 10" .17HM2.
