Rebarrel quandry

[Aitch]

I purchased a .284 heavy barrel to mate with a Rem 700 action. The issue; the barrel has 1.062 x 18 thd and the action is 1.062 x 16. I planned to rechamber the 30" barrel, as in staying with the .284 chambering and moving the chamber forward enough to rethread the tenon. I realize the simple solution would be to spend the bucks and buy a compatible 700 clone action but I've already bought the Rem 700 LA. I am wondering if it would be possible to rethread the action simply by chasing the existing 16 tpi threads with a 18 tpi tap? How much strength would I give up? Other options?
The barrel only has 600 rounds down the tube and barrel scope shows virtually no erosion so I really hate to touch the chamber.

OH MY. don't even think about it. sell one or the other. Threads have to match and they need to be very well done. --Jerry

Cut the 18T.P.I. threads off, turn it to 1 1/16" and re-thread it to 16 T.P.I. Then, deepen whats left of the chamber with the proper .284 finish reamer and set the proper headspace.

What they ^ said

Yea what they sed. Simple enough. Gonna have to headspace and fit it to the action anyway no matter if it had 16tpi

In re-threading/chambering you may extend the useful life to boot as you will be cutting out about .70" of throat. Keep your action as is and you will thank yourself the next time you put a barrel on it.

Destroy the cheapest component first.

I thank all, and I agree. I just wondered how much tensile strength would be lost in that rethreading process. And yes, I'll continue with my original plan and move the chamber forward.

I think just to answer your question of putting an 18 on top of a 16 youd end up with an unusable thread that looked like a dremel threaded it

Ever tried threading a metric nut on a bolt? thats whats gonna happen but way worse. Your gonna ruin both the action threads and the barrel threads.

Listen to the smarter people just set that Bit$h back and be done with it. No reason to ruin the action.
