Let me see here. You have some old 3006 barrels, You are willing to by a reamer. If you do it you probably have a lathe. So you will be out 175.00 for the reamer. Or you will buy the reamer and a friend will do the work, or you will buy the reamer and a smith will do the work. The smith will charge between 75 and 150 so you could potentially spend 275 on a used barrel that may be too short. Or you could buy a wilson from Ragged Hole Barrels (Barrel Bros)a sponsor on here and get a brand new barrel. Close to the same price.
