Pre-'64 M70 and single-shot feeding

Is there any problem with feeding one round at a time(not from the magazine)? Something I read here a while back made it sound like it just wouldn't work. I've never owned a CRF rifle so I have no idea.

Also, what are the aftermarket cures for this action's gas-handling shortcomings?

Thanks, Lee

I normally single load my pre-64's by snapping one in the mag and feeding it home. It is delightful to see how nice they feed. But, if you must stuff one in the breech and close the bolt after it (Like if you want a full mag and one in the chamber), go ahead. Just force the bolt handle down, and the extractor will snap around the case rim. I polish the front of the extractor to help this (can't say if it really helps).

Mine doesn't mind, but why would one do it? It takes only a tinny bit more effort to push the cartridge down until it snaps into the magazine as it does to just drop it on the follower.

To be anal about accuracy; to keep bullet seating depth and concentricity the best it can be. It would be for a long-range crow gun.

Thanks

Get a single shot follower, available from Midway. It sit's on to of the regular follower, and has a dished surface that you lay the shell into.
Otherwise the best way is to squeeze the extractor ito the bolt body (with the fingers of your left hand) to force the claw to open as you close the bolt.

I think you are overthinking this. Push the bolt in slowly, with a round feeding from the magazine, and you'll do no harm to it.

Otherwise, just buy a Remington.

A properly set up control fed rifle WILL NOT close on a round dropped down into the chamber..If it does your gun has been modified..You can make one feed by pressing very hard on the extractor while closing the bolt but thats a worthless manuver....

You can easily modify a control feed to take a round dropped in the chamber, but it will weaken the extractor and thats not smart on a DGR..

CFRs were designed to feed from the magazine and thats the best and fastest way to feed a bolt rifle, you still have to close the bolt and I have seen too many rounds fall out in the excitment while trying to drop one in the tube..

Well, CRF problems I don't have, no trouble to
get an extra round in my rifles, never had
feed problems to speak of.

Seeing as no one has had the decency :-) to ask
about my new (second hand) .458 Win Mag Mod 70
PUSH FEED, made in 76 and marked super grade (would they lie?), well I won't mention it.

Anyway still waiting for the government to say
I can bring her home.

Then if IT won't feed reliably I'll eat crow and whinge like a stuck pig.

I think that the pre-64 model 70 was designed to feed single shot off the top. All of my rifles well even the like new ones. I think it was done by design since it was modeled after the Mauser and Springfield. The Springfield was designed to shoot single shot with a full magazine. I like having four down and one up the pipe on a safari rifle. Somewhere I remember in the Winchester literature(new) that the magazine capacity on the magnums was three and the capacity was listed as four. I am working off memory so don't go by that alone. I do think it is true.

Since none of the M70 fans are willing to help you with this design issue, I'll wade in.

If you are determined to keep a Fixed Ejector, Controlled Feed rifle, you can:

1. Load sensably and keep the Internal Pressure at or below SAAMI Specs.

2. Rotate your cases to the "Recycle Bin" a bit quicker than the ones you use in your Push Feed rifles.

3. Rechamber for a Belted Magnum case which is stronger than a non-Belted case in the area you are concerned about(while still doing #1 & #2).

4. Rechamber for one of the new WSMs or the ShortWSM(whatever that name is). They also have thicker Caseheads "according to" some of the folks who have sectioned them on this Board.

And finally the best option to deal with your concern:

5. Jack up the scope and swap the rifle for a Push Feed of your choice.

A model 70 with a follower that has been properly set up will allow you to lay a cartride in the loading port and push it home. No snapping over rims or squeazing required.

I hate to disagree with you , Ray, but:

From "The Rifleman's Rifle", by Roger Rule, page 8, describing the M54 Winchester,(predecessor of the M70):

"The non-rotating extractor, of Mauser type is attached to the bolt with a collar...the extractor is quite heavy, its forward face well-beveled so it can easily snap over the rim of a cartridge placed in the chamber ahead of it."


From the instruction manual included with a recently purchased CRF M70, page 17:

" With the magazine loaded to capacity, an additional cartridge may be placed directly into the chamber..."

The M70 extractor was designed from the get-go to snap over the cartridge in a single feeding scenario. The Mauser on the other hand, was not....Not all CRF's are the same, though they may appear to be without closer scrutiny.

The last thing that I would want is a DGR rifle that can't single feed a cartridge into the chamber. Of all the rifles to be able to accomplish such a task........that's number one on the list.

I agree with Matt totally. Other than single feeding and top loading. The main reason for doing so is this. Suppose it were possible to fail to extract a spent case. If you could not recycle the bolt and slip the extractor over the rim you would have no other option but to beat the case out of the rifle with a ramrod. Not easily done if not prepared.
