Rechambering a 30-06 into 300 Win Mag

[Basque1]

Do you need to rebarrel a 30-06 bolt action rifle if rechambering from 30-06 to 300 Win Mag? the twist now is 1:12
Thanks

Different bolt face diameter.
Barrel needs setback.
30 cal barrel can be rechambered but why.
Not near enough information. Use the search function

I realize that chamber work is required, however, want to use the same barrel since bullet diameter is the same

Well you’ll need to either cut your bolt face open larger or get a new bolt fitted.

To use the same old barrel will take as much work as a new good barrel and you’ll be left with something that’s still used when it’s “new”. And that’s if there is even enough meat on it to rechamber in the first place. Don’t waste your money trying to redo an old barrel, get a new one.

It’s allot of work to get minimal results, you can work up a 30-06 load to come pretty close to winmag performance as long as the barrel in question isn’t an antique.

Do it right.

Buy a new .30 cal blank, 10 or 11 twist depending upon the length of the bullet you plan on using. Then have it chambered/installed by a reputable gun smith.

That should cover a vast majority of use cases for the win mag.

What they said, new barrel.

Not that you give a shit but I'd keep the 06, develop a load that gets you fairly close to WM performance. Save your shoulder, a bunch of precious powder and go thump things out to 1000 and beyond.

Unless you have access to free gunsmith work, run the numbers and see what the total cost would be vs buying a new factory rifle in 300wm, assuming your current rifle is a factory gun.
At the end of the day, just about anything is possible with time and money, but you have to make the decision if the time and money is worth it to you.

I've open up a couple of 1903 Springfields to .300 WM, it was common practice when the .300 was new. The bolt is hard as hell, you have to run it fast and use carbide. The extractor requires a little hand fitting. What make and model is the rifle?

US-17 Remington 30-06 Imp. Brand new barrel, do not want to change it.

I meant "1903 Springfield " the enfield rifle is similar, it can be done. The trick is to nail headspace right on the nose or you have to set the barrel back a full revolution and recut the cone breech and extractor slot. A lathe man should be able to do it.

Yes I understand the work that has to be done when rechambering, I was trying to reaffirm those thoughts with other eyes on the project. I appreciate your input. Be safe mate. And no I do not own a 1903 Springfield.
