Chambering a 700 for 30-30 win.

I was wondering if anyone had any insight or experience with this. I was considering building a 30-30 hunter class rifle.

I was thinking I could modify the rims to fit a .308 bolt face in a r8 collet.

How would I get the headspace right?
 
If I understand what I think you are asking, you simply headspace the 30/30 off the shoulder with a normal 30/30 headspace gage. Even though the 30/30 is a rimmed cartridge it still works best headspacing off the shoulder.

We decided that long ago with the 30 Herrett and 35 Herrett in the T/C Contender.

I see a couple of choices. 1. Use 30 Remington brass 2. Turn the tenon like an old Savage model. Use a Sako style extractor.

Turning 30-30 case rims to 30-06 diameter for use in bolt action rifles is as old as dirt. And it is also new, in cases such as the 30 Aardvark, a very good HBR cartridge, BTW.

The 30 Remington is certainly an alternative but it presents it's own set of problems because of its unique case head diameter.

As Jerry said, you simply headspace off the shoulder, the same as any rimless cartridge.

I believe the old Remington 722 was chambered for the 30-30 at one time. It is a surprisingly accurate cartridge limited only by the lack of good brass. Unless you can get your hands on a bunch of the 30 American cases.

That was kind of what I'm wondering, will my 700 extractor work once I've turned the 30-30 cases down?

I have not bought a specific action, I was going to use a 700 sa I have in the shop, but I could get a sako action, or use a sako extractor.

If you turn the 30-30 rim to the same configuration and dimensions as the 30-06 or 308W they will work fine. As I said before, this is something that has been done for the past 75 years or so.:cool:

Ok, I was responding to rustystud's comments that made me believe that the extractor would not work once they were turned.

You might want to rethink that cartridge choice...

I believe it has been tested long ago and is not as accurate as .308 Winchester variants ...

I have not bought the reamer, believe me, just wanted to get some experience on it.

It's intuitive that if it were an accurate round, folks would be competing with it.

Still leaning toward 30x47 or .308 variants for the Hunter class.

Thanks for your insight

30-30

Some pretty impressive HBR Rifles have been built in 30-30, but it is usually a improved version.
Sam Weaver had a Rifle in 30-Aardvark and one in regular 30-30 that was as accurate as any HBR Rifle I ever saw.
Lets not forget about that shooter named Micheal Turner who shot a 30-30 about 5 years ago that headspaced on the rim. He actually won some aggs with that thing in the Gulf Coast Region.
One thing that you need to be cautious of if you set it up to headspace on the shoulder. The 30-30 is not that thick between the face of the case and the solid part of the web. If you counterbore the barrel a little too deep, you can uncover the web, resulting in a bad situation..........jackie

How would you headspace off the rim, and be able to extract?

This brings up a point that I would like to ask. Why is it that people have tried to discourage me from belted and rimmed cartridges in benchrest?

The obvious answer is the headspacing, or datum point.

In my mind, once a case is fired once, and neck sized after that, it's not an issue anyway, since the brass fireforms to your chamber.

I was looking at some 1000yd scores last year, and saw 300 mag all over the sheets.

This seems like another herd mentality statement people make? Or is there something else i'm missing about the headspace science.

I think because a rim or a belt do nothing to contribute to accuracy (so why bother with them) and because the capacity of the belted cases is not required in Centerfire Benchrest Shooting. (100-300 yards)...

Even the little 6mm BR isn't a good as the 6mm PPC in Centerfire Benchrest Shooting. (100-300 yards)...

But it (6mm BR) performs well out to 1000 yards ... http://www.6mmbr.com/page/page/1309618.htm

As designed, most belted magnum cartridges were intended to headspace off the leading edge of the belt. However, it is still possible to headspace the cartridge off the shoulder. Most long range prone shooters using magnums (both past and present - today, belted magnums are a dying breed in prone shooting due to recoil) headspace their rounds off the shoulder of the casing.

I suspect long range benchresters also headspace their magnum rounds off the shoulder, and not off the belt. I say "suspect" as I don't shoot benchrest in any form.
 
The best way would be to alter the bolt and use a non-rotating extractor. A ruger would be fine. Second best would be to alter the bolt and use a sako type extractor. Headspacing is done on about 5/8 of the circumference of the rim.
In general, headspacing off the rim or off a belt is avoided because it is very unforgiving. If you headspace on the rim, a rim which is .0005" too thick will make closing the bolt very difficult if not impossible. So, in order to do so, the rims must be uniformed. Generally speaking one is best off with about .001" headspace on the rim (this is how I set up my 303 British). Belted cases present the same challenge only moreso. The variation in belt dimensions make the use of the belt in headspacing very difficult. In either situation, the cases can be headspaced on the shoulder in which case the rim or belt becomes superfluous.
People are trying to discourage you from using belted or rimmed cases for BR out of a sense of self presevation. They know these cases will work better but have avoided using them because they have invested heavily in 6PPC stuff. If you start cleaning up with a 219 Zipper, they will all have to switch in order to remain competitive. They won't be able to give that PPC brass away! Regards, Bill.
 
self preservation:rolleyes:
the PPC is a dying breed in group shooting >>>>
