Contoured or straight pipe barrel blank, your chamber reamer cut to YOUR specs, (that you custom ordered way ahead of time) shipped off to your FAVORITE smith, threaded and chambered, returned whenever they get around to it. Cost less than say $800.00 +? That's with the cost of the reamer and which will be a one time fee. In my case, I ship my contoured barrel and my custom ordered reamer off to my smith, he threads the barrel and chambers it in about a week or so and has it back to me in nothing flat, as long as it isn't hunting season. Never a rush and he's all over it. Maybe in the $200.00 to $300.00 range and NO I won't tell you his name. With a nut, spin the barrel on , set the head space to YOUR specs and go shooting. Don't like that caliber? Order up another barrel, find or buy another custom reamer, have it threaded and chambered, spin it on, set the head space and go shooting. Shouldered barrel? The barrel AND action is down and out till the smith can get to it. Shouldered barrel cut WITHOUT the action? You won't know till you get the action and barrel put together. Sum sing wong? Ship BOTH the action and barrel back to get ironed out. Now you wait. All of my Savage rigs (I think I have 5, I'd have to look) have the nut. All shot bug holes. If I don't like that caliber or want to try something different, I don't have to depend on anybody but myself to spin my barrel on so I can go shooting. I'll take the nut job any day.
