I have done quite a few, for an amateur, with good results. I now use a long, centering handle from Brownell's that uses two pilots, in the bore. It works from the breech end and I added a chamber pilot, made from a plastic snap cap. I use an adjustable reamer and a half-turn on the adjusting nut gives me about .002-.003". When I'm about .001-.002" from what I want, I finish it with a brake hone type tool, also from Brownell's. Like Ctroy, I do it because I want to. It's not brain surgery. In the earlier years, I did several from the muzzle, using a guide I made from a 3/8" rod with a plastic jag on the breech end, also with acceptable results. I like to put the barrels in a vise vertically, so there is less likelihood of leaning toward one side or the other. Some had a parallel section originally and some did not. The Lefevers have a continuous taper with no parallel section. This, I think, is where the bogus claim of a continuous taper from the chamber story came from.
If you want a pro, I'd certainly recommend Mike Orlen.
