Model 70 Question, hopefully not too dumb

JohninAB · #1 10-06-2011, 08:58 AM

I have a pre 64 Model 70 chambered in 270 Win. Was wondering what other chamberings I could chamber it in based on the action length. Am I stuck on having to chamber it in something based on the 30/06 case?

Its not only limited by the length of the action....but the size of the bolt face is likely more limiting.

.240WBY, 6mm-06, .270WIN, .25-06, 280 REM, .30-06, 35 Whelen are ones that come to mind....

I've seen them rechambered to 270 weatherby.

That would involve changing the bolt face as well I think....do you mean .270 AI?

Not sure about the bolt face but no it was a weatherby. I've seen a few of them actually. One of the gunsmiths on here could tell us I'm sure if the bolt face would have to be changed. Been thinking about getting it done myself-just hard to find a left handed 270 with a 26" barrel.

Should be able to re chamber it into alot more than just the 30-06 parent case stuff. A friend of mine had a 270 re chambered in to a 300 win mag. They had to open up the bolt face and had to have a sako extractor put in (they are nicer anyways) but it can be done! Not sure what the max would be though. I've also heard of 30-06's being rechambered into things like 7mm stw's that are an ultra mag length so anything is possible!

I would think anything on the 06 case without much modification, if any. In fact even anything on the .308 case, your mag will just be longer that necessary.

Open the bolt face and extractor and I think you could do any of the 'regular length' magnums (7mm Rem, .300Win, .338 Win etc up to .458Win) up to the .300Win case length (most of that family are 2.5", Win is 2.66" case). Not sure what kind of mag modifications would be needed but I would think at least the rails would need work then.

You could do the longer magnums on the 2.85" case (from 7mmSTW - .470 Capstick) as well but that would require a new magazine box (3.6" length box I think).

I don't think one would do a sako extractor on a Winchester. That's a Remington upgrade. Rechamber you can go 270 Weatherby. You will have to open the bolt face and maybe the extractor too. A rebarrel and the sky is the limit up to 500 Jeffery or whatever. It just takes money.

Just wondering if there is something seriously wrong with the way it shoots now as a .270 Win.?

Why do you want it in a different cartridge?

Leeper · #10 10-06-2011, 10:46 PM

Being stuck with cartridges based on the 30/06 is not a bad place to be. In fact, I would hesitate to alter a pre-64 action to a magnum boltface unless I wanted to barrel to 33 caliber (338) or larger. One thing about opening an action up is, you can't go back.
If you do want to go with a larger cartridge, opening up the bolt face is no big deal although it is, as I said, irreversible.
Good cartridges in a pre-64 if one wants to open it up, would include the 338 Win Mag., the 358 Norma, and the 375 Ruger. One could also barrel it in one of the smaller magnum cartridges like the 270 or 7mm Weatherby, the 264 Win mag, or the 7mm Rem mag. None of these under-30's would be my choice but it's not my rifle!

Yeah....why not keep it the way it is and just buy another rifle in whatever calibre you want?

He could go buy a pre 64 in a magnum caliber like he wants.

Tone · #13 10-07-2011, 09:10 AM

That's what I'd do too! Cheaper in the long run too probably! depending on what all you are doing of course!

#14 10-07-2011, 10:06 PM

a 6mm-06 or 6.5mm-06 would be nice.

Don't try to improve one of the finest rifles ever made. You'll ruin it.

silver lab · #16 10-09-2011, 12:31 PM

Are you rechambering or rebarreling it? If your puttin a new barrel on you have so many options based on the action length. If your rechambering it 270ai,270gibbs,270wby and theres prob some more out there as well.

Like Bill says, when you open up the bolt face you can't go back...last winter Bill opened up a Pre'64 for me and rebarreled it to 308 Norma.
There are LOTS of options with a 30-06 bolt face and magazine.
Bill is doing another Pre'64 Model 70 to 280 Ackley for me and the next Pre'64 I find with a 270/30-06 bolt face and magazine that's not in really nice shape will become a 35 Whelen.

Just curious...
What does the butchers bill look like when you have that sort of work done?
Are we talking a few hundred or a couple thousand?

Dont mess with such a classic rifle just leave as is. Or sell it to someone who appreciates it. But at the end of the day it is your gun and your choice.
