I didn't think it was possible.
The magnum receiver is steel, and has different specs.

you cannot, the receiver, the bolt assy, and other parts are diff, there is too much a pressure change, even if you change out all theparts, but leave the regular receiver, you are still risking tearing that receiver apart.
The operation of converting a Ruger 10/22 from .22 lr to .22 mag cannot be done by simple drop-in parts. The overall lengths of the cartridges are different and, as noted, the aluminum alloy 10/22 .22 lr receiver cannot handle the force and pressure of the .22 mag (and .17 HMR).
A conversion for the operation is available as described in Rimfire Central but will require significant receiver, trigger housing, bolt, etc. modification. Due to the alloy receiver, there have also been reports of the receiver not holding up to this conversion. In short, it can be done but will require a lot of work and things can/will fail down the road.

It would be easier and better to just buy a 10/22 mag rifle from Ruger. Looks the same, but it ain't.

I think the 22mag bolt is made of tungsten the original is steel.

They are both steel.

That would be great, but they discontinued it shortly after it was introduced.
It is no longer made, and was only made for a year or two.
One could assume even Ruger had problems with the all steel .22 Mag receiver or something.

1) Remove the stock from your 10/22.
2) Open up the stock to accept the longer 10/22 WMR magazines.
3) Purchase a 10/22 WMR complete barreled action. Discard your 10/22 action.
4) Insert the 10/22 WMR action in your modified stock.
Voila!
Too bad Ruger discontinued the WMR version. Remington offers a 597 WMR that might be worth a look.
My memory is that the WMR 10/22 had a steel receiver (instead of aluminum) and bolt was steel with tungsten inserts, to get enough mass while fitting in the modest sized receiver. IIRC there is also a stern warning in the owner's manual not to shoot more than 50rds between cleaning the barrel. I think the issue was rounds not fully chambering and then having a kaboom at the unsupported wall near the head. For me this warning, plus WMR ammo costing more than 9mm (at the time - 2-3 years ago) killed my interest in the concept.

The 10/22M was in production for about 8 years.
The gun had problems from the start as a .22 mag platform, the most significant problem being ejection/feeding. The gun would not reliably eject the .22 mag case without stovepipes. This was before the introduction of the .17 HMR. With the .17 HMR, folks, including myself, were modding the 10/22M with exception terminal results but it yet retained the ejection problems. (My failure rate was hovering around 50%. The tight groups the gun provided, however, was enough for me to keep at it to get the gun to run reliably.) Numerous modifications to the design were made to the gun to make it reliable.
With the progress the folks were having with making a reliable 10/22M (in both .22 mag and .17 HMR), Ruger made some design revisions, the most important (for them) was to include a second inside extractor to the bolt. Unfotunately, this didn't do much to help. What folks were doing to, even with the single extractor bolts, to make extraction reliable was to replace the factory extractor with one that has a sharper point to the hook, e.g. Volquartsen Exact Edge, etc. This simple drop-in part had reduced my failure rate down to below 1%. (Other mods such as rounding the lower rear of the bolt, smoothing the bearing surfaces, etc. also help.)
With the new mods by the factory, the 10/17 was just about to be released when it was cancelled and died on the vine without (that I know of) one sample ever reaching the sales counter. The reliability issue was just too persistant, IMO, for the gun to make it and, IMO, I don't think Ruger was keen on using other folk's pats in their guns. (Why they couldn't just sharpen their extractor is beyond me.) Also, the 10/22M was never a really big seller. Where you can get them new when they were offered in the $350 range, they are now commanding at least $500 used.
Keep on searching shops and shows, you may eventually stumble onto one as I have done a couple of times (and promptly bought them).
