You'll be into a gunsmith probably more dollars having him cut the barrel back at least the thread length then chambering and hoping the new chamber goes in dead nuts and takes out all of the old one.
A new McGowen blank is $165 and it gives a gunsmith a clean canvas so to speak, in my mind the new blank gives me better vibes
I'll second the above quote. Buy it cylindrical, not contoured. Chamber both ends (example; if you've got a 6.5mm x 284 and a .260 Rem or 6.5mm/06,,,,,, pic two). I think a better solution would be to have the barrel (on your custom) salt bath nitrided. Then just fire form in the original chamber. As mentioned in an earlier post, many times accuracy is very good when fire forming most Ackleys. I've shot a .22/250 AI for years. Fire forming always gave me "minute of prairie dog". Besides, nitriding would cost less than a barrel blank from McGown, not to mention the threading and chambering costs.

Turning .0125" (that's twelve and one half thousants) from a Remington tenon isn't going to 'clean-up' the 16tpi. You'll still have part of the old Remington thread. I know of no way to magicly turn 16tpi into 20tpi. Also, cutting the treads completely off will not leave you with much shank to turn down and thread. Remington factory barrels just don't have much 'extra' shank, neither does Howa (Howa shank/tenon is metric, measures 1.020" I think). So, it seems to me, if you're going to use a Savage action the easiest route would be to use savage 'take-off' barrels (of the proper bore & groove) and set back and reamed to your specs for fire forming cases. You'd have to be picky to be sure the new chamber would completely remove the old one. And besides, you'd have that interchangable bolt head, too. All of this ignores the problems related from using brass fired in one chamber in another. Sometimes it works,,, sometimes it doesn't.
that's exactly what they did. Cut the Remington barrel thread off and then turned down the larger O.D. to fit their needs. There was a guy that used always had them for sale on Gun List for a very cheap price. These guys must have bought a dozen barrels from the guy in different calibers. Some went on Remingtons and others went on Savages and at least one Winchester. But this was before anybody offered the Savage prefit barrel as an option.

Re: Modify Other Barrels to Savage Barrel Nut?

I think I read one post that actually addressed your question.

The answer is yes, you can do it and without cutting the remington threads off.
Turn the area behind the lug down to 1.055 for a small shank nut and to 1.120 for the large shank(prefered?) and cut the 20tpi threads. I use wires to measure pitch diameter to get the threads very close like in class 3 threads but that is for savage action to barrel fit. Cutting the threads class two or looser is probably OK for just the nut. From there setting the headspace is simple as screwing the barrel in or out. The only thing you need to watch out for is for the tendancy of the barrel to turn while you are securing the nut. Well... and the slack in the remington threads.

This can be done for for any take off barrel and no other machine work required to make it fit and headspace. I think it would even be feezable to use a jam nut or a half dog set screw with the proper pocket machined to maintain headspace for quick installs and removals.

I must add that if you wanted to rechamber you could do it like above or lop of the threads like others have said. If you do so often the diameter of the barrel reduces rapidly and may completely change the harmonics(accuracy) possibly even becoming slightly more dangerous if using full power loads.
I aim to be the man my dog thinks I am.

Re: Modify Other Barrels to Savage Barrel Nut?

G'Day Fella's,

Montana Rifleman, I have contemplated making up a couple of these barrel nuts for some of my Rem 700 rifles, for years now! Unfortunately, I've been a bit busy with other projects!!!
I have seen that the barrel making business in Spain that Ed Shilen help set up, make just these replacement barrels and barrel nuts, for Rem 700 rifles!
Try www.bergara.com or go Google up that name + Barrels and see what you find!!!

Hope that helps
