rinoray, I guess it's a matter of perspective. For a gunsmith with the correct action wrench, barrel vise, chamber reamer, gages, a lathe then it's not all that difficult. You can get by without a lathe if the barrel is short chambered. Then the chamber only needs to be deepened to get the correct headspace and you can do this by hand. I wouldn't recommend attempting it without the other tools listed. A book that will help you is The Complete Illustrated Guide to Precision Barrel Fitting by John Hinnant. Brownells sells it. George
