Rem 700 receiver thread accurizing

[hemiford]

Factory 700 RUM action, E-serial number. (~~2000-2010 production).
Best I can determine, on my own, is that this particular action is already pretty good, with respect to machining straightness.
The front receiver face seems to be very square to the body.

If I have the barrel threads cut oversize, for "accurizing" purposes, they are now a custom thread. I'm considering having my Smith
do this operation because it's getting a new barrel, and the new barrel threads will match the new receiver threads.

But what if I subsequently get a different barrel ?

How will the next Smith, who might be different, determine how to cut the new barrel threads to what are now custom threads in the receiver,
not standard 1.0625 x 16 Remington threads ?
How does a machinist determine and match custom threading ?

I'm worried that cutting oversize threads into a receiver renders the receiver a Useless Bastard Child.

Its a very simple and straightforward matter for a decent gunsmith to match any barrel threads to the receiver. The barrel is always cut to match the receiver no matter the spec. Just be sure to let your gunsmith know ahead of time.

All of my threads on my custom actions have the size noted. Seeing as I run switch barrels with just about every rifle, this is simple to do on each barrel.
Secondly, the squareness of the action matters not to the action body, it matters to the centreline of the action and bolt, which is why ALL aspects of the action and bolt are 'blueprinted', including bolt lugs, lug recesses and barrel shoulders. I also go the extra step of using pinned recoil lugs on Rem 700 or other separate recoil lug actions.

Cheers.

What He Said ^^^^^^^^^^^^^^^

I have my gunsmith write on the bottom of the barrel anything special,
Twt rate, grooves....
To add I have him index both, so if I ever remove it.

the next Smith measures the barrel that you brought it in with and if he's worth his salt measures your action and the barrel tenon before he spins the new barrel

Unless the action is really bad then just have a good smith install a top quality barrel without recutting the threads. Properly bedded in a good stock, quality scope and good handloads. Chances are very good that it will shoot as good as you can hold it.

If you plan to buy/run a pre-fit barrel iin the future it limits your choices . But usually once you buy a custom you don't go back to pre fits

IMO, if this is a complete rifle, you are better off selling as is and using funds to buy a custom action like a Zermatt Origin. Then shave costs with a KRG Bravo, pre-fit barrel and a sub$3000 optic.

A recut 700 offers no value as the basis of a custom and can/will disappoint.

A recut 700 offers no value as the basis of a custom and can/will disappoint.

How so?
If done correctly, it will mirror any custom action.
Where is the value lost to a custom action?

Cheers.

assuming we're talking about an origin instead
being made of lower quality material, lower quality machining, worse ejector, worse extractor, not Savage thread, no interchangeable bolt heads, harder to resell because it says Remington on it, cheaper bolt.

if done properly the blueprint and bolt work will give you most of the origin stock features and it will most likely shoot as well but it won't have the barrel options and barrel pricing the origin will and it won't feel as good usually
