Could you take a few close-ups of the bolt, bolt face and extractor?
Does your actions have a circle Z on the left rail?
I've still got a cravin' for one more rifle and I have a fantabulous piece of sun-ray fiddle back Bastone and several barrels to choose from....
 
THanks for the bolt pics. That could be a Rhimakki bolt with a M-98 shroud on it! The extractor is the same as the Rhimakki (and Mannlicher Schoenauer) and $*&#^ TOUGH to make!!

Two more questions, if I may-- Are the bolt shround threads Mauser buttress or is it keyed in like a Sako?

Do your markings match these?

Guest 206-- Interesting photos. Its not often you see a speed-locked M-98! It looks factory, too.

The two screws on the cocking piece means its held on differently that a true Mauser. (And takes away a lot of my interest in the action)

THe threads I'm referring to are on the bolt shroud. Mausers have a buttress thread there instead of Vee form.

Neither of your bolts have a shroud lock so the end of the cocking piece serves that function. That means the cocking pieces probably have a 3/32" cross hole near the end of the shroud. If you pull BACK on the cocking piece just that .020 or so to completely uncover that hole and run a pin through it, the entire rear portion of the bolt with shroud, cocking piece, main spring and firing pin can be simply unscrewed from the bolt.
Correction both your bolt do have shroud locks, so to unscrew the shroud the cocking piece has to be pulled back and held back by the cross pin AND the end of the shroud lock pin pressed inward. THEN the shroud will unscrew.

Call me lazy, but I don't want to have to make a M70 safety from scratch for an odd-ball thread. If the mini-Mauser has buttress threads, I'll buy an action today because an aftermarket M70 safe can be fitted and I already have a couple.

Do you have the capability of measuring the bolt body diameter? I'm assuming .703 but they could have changed it.

stevelyn-- Charles Daly LEFT HAND actions are worth big money these days. There were very few of them made first for PO Ackley and then Daly by a Japanese firm. I've only seen one.
 
Thank you! You saved me some cash!! The bolt shroud would have to be made from scratch in the M-70 Win design and that's a 'one and done' deal on manual machines.

Really odd to see a Mauser rear set on a Sako Riihimaki front!! And that's what it is. I'm going to buy $500 worth of those extractors and forget the action. ;)

Interesting that a left hand action is now being made in Europe....and glad to see it. Maybe CZ started a trend.
 
What has CZ got to do with it has been my question all along. If not, why their logo on a Zastava action?

"Sako extractors" as put in Rem700 bolts are entirely different and run by a coil spring and detent...same system as Rem 1100/870 and hundreds of others.

The Riihimaki action is called that because that's how they were advertised and sold in two sizes. they later carry a model number. Ithaca is a small town in New York, too.

Their extractors are M-S types that are spring steel on a linear dovetail. If they could be bought, people wouldn't pay $200 to have one made from scratch! Thirty years ago, I heard of a 'mini-Mauser' with that type extractor. This must be it! I have an action that needs one....and I have a craving for one more .222.

What other action is push feed with a M-S extractor and fixed ejector? Mannlicher-Schoenauer and Rhimakii marked Sakos. Any others?

I'd still like to see one of these 222 size mini- actions, but not $500 worth. I AM looking for parts, though!

Obviously you have resources available to straighten the record or links to it. How about showing it.

I'm passing on what I've heard for the last 55 years (I was 15 when the guy told me to, "look for the 'clip'. Those are the nicer ones called Riihimaki". ) That was at a gunshow in 1961 and there were several there. When I became the gunsmith in 1969 we almost always had a couple in the used rack, they were on the books as Riihimaki, xxx caliber. If they were marked differently, they were listed by model number. I bought a heavy barrel .222 in 1970 that I still miss terribly. I've got four rifles or foundations of other rifles now.

I would LOVE to know the sequence of changes seen in these rifles. When did the trigger guards go from stamped to forged? When were the white line spacers added to the stocks, when the change in comb flutes? WHERE can I find a 22 Hornet to fit the magazine I've had for 40 years?! What calibers were they made in? A really odd 25-20 just changed hands in Florida that I'd never heard of.

How rare are small, 222 size solid bottom single shot actions?

There was a guy for Sako that used to come to Twin Falls, ID every spring to shoot rodents...'Ari' is the only name I know. He brought eight of those cute actions in about 1994 but all were spoken for and he couldn't get me another one. I'd give a finger to find one.....

Always feel free to correct me when I get something wrong. That's the way I learn.

A currently made and used Sako extractor is a 'lever driven by a coil spring'. The early ones are a leaf spring shaped with an extractor hook and stop surface that is held in by linear dovetail. The early part is ONE part. The current extractor is three parts. They're cheaper that way. :cool:

I'll pass on the used one for sale. My home-made model is working but weak and not reliable. BUT, I have four Riihimaki 'variations' of Sako rifles that can interchange bolts without a problem. The rebarreled .221 Fireball and the two re-barreled 6mm Cheapshots have exactly the same bolt to chamber dimensions as the original .222 Rem sporter. The Fireball broke the extractor at just over 3300 rounds. I went to 3500 and set the barrel back and made an extractor that's still in it and still shooting, but not the 1500 rounds a season it did for several years. Not long ago, I put three rounds into .360". That was the first paper that gun has shot since 1988 when it did the same thing in load development. Re7-- the forgotten small case powder, in my opinion.
 
Awaiting confirmation now, thank you.

When I started gunsmithing in '69, Sako L61 actions were cheaper by the half dozen from Brownell's. I barrelled all six to 25-06 with SHilen CM#4s and stocked them with outrageously figured Claro Walnut from CaliCo Wood Products. The president of the FL Senate got two, and the other four went to people he knew all over the country. Another L61 was barreled in .358 Norma Mag and yet another to .263 Sabre for my boss at the gunshop. One of the 25-06s was stolen, rusted and recovered. A cop friend of mine bought it and gave it to me. I rebarreled it and gave it back to him. His son killed his first four deer with it and claimed it years before his dad died and made it officially his.

I wish I had trackers on my guns!

One more question that might be of interest to the group is the history of the M-70 (type) triggers on Sako small actions. All mine have them.
