The worst case would be that this barrel would headspace too large or too small in your particular action. These conditions would require either that the barrel be set back on a lathe or, in the second case, your chamber be reamed longer. The Brownells shop survey puts the installation of a pre-chambered and pre-threaded barrel currently in the $75-$150 fee range. It depends on your area. Setting the barrel back just a few thousandths or extending the chamber by reaming it a little will likely add to this by an hour's time plus reamer rental or ammortization cost. If your area is on the high end of the price range, you can buy the tools and rent the reamer and headspace gauges to do the job yourself for about the cost of having it done. You won't save anything and you will have an inexperienced gunsmith doing the job, but you will then have the tools for the next gun. However, if you need to set the barrel back, you will need a lathe, and that tool won't fall into the shop price range.
