I am going to have the barrel cut down on my .308. I have seen multiple types of crowns and I am curious what if any benefit one has over another. I would assume the recessed style would be more appropriate for a rig that will be regularly drug through the field for hunting purposes? We don't have any good gunsmiths in the area and I'm not looking at spending the money to ship it to one at this time. I am going to buy a new barrel soon and will have a professional do the work at that time. For now I simply want the factory barrel cut to a more manageable length, 20". Is this something I can count on "Bubba" to do without problems with accuracy? The reason I'm asking here is because I know this conversation will be useless with the local 'smith. I am going to have to be very specific with him in what I want and how to do it I'm sure.
