I have a Savage 24C that has seen better days, cosmetically. The lock-up seems quite solid, bores look fine, action springs, firing pins and trigger / sear /hammer all seem to work properly. The stocks are a mess and the metal finish is showing much wear. I've seen that this rifle, in the J-DL version, was supplied in 22 Mag over 20 gauge. Is there any reason that I could not re-chamber this one to 22 Mag? I can not find any information for or against the idea that Savage actually used different bores for the two versions of rimfire that they sold. If someone has done this, how did it work out?
 
I do remember reading something on the internet a few years ago about it being done successfully. I can't remember where though. There is a forum called savage24 you may want to check out. Alot of knowledgeable people on there when it comes to anything to do with the 24's that I'm sure could answer this question.
 
The brass diameter is slightly different, i would imagine it could be reamed out, probably wouldnt take much. I have fired LR in a magnum revolver cylinder, some of the cartridges were slightly split, but not a huge difference, it was only after a while I noticed I had the wrong cylinder in the revolver.
Just my thoughts, I am not a gunsmith.
 
I have re-barrelled the upper .22 with a new .224 bore and chambered the new barrel in .22 WMR, never had an issue strength wise. Not a task for the faint of heart though...
 
This debate has been going on for ever! I think I ask the same question, about a year or so ago. And it looks like the same answers...will it work ... yes... It might work very well, but may not....
I have one in 22 mag/410, love the little rifle, shoots very well. I looked for year! For a 22mag/410.
I do think it could be done, but have a gun smith check the bore, just in case it too tight.
I have a couple 22 mag,and this one is a pleasure to shoot , maybe because of the extra weight of the two barrel? .. I don’t know, but a very likeable little gun.
And still very expensive And collectable for a rifle of its kinda. FYI the 22mag/410 was the lowest production run made of the model 24s
Have fun and play safe!
Cheers

Nice to revisit an older post.

The twist rates are the same, the bore diameter is not. Swaging down .001 on firing shouldn't pose issue. The chamber, and extraction are what require effort/attention.
The action itself is plenty strong for the conversion.

There are a few popular .22 rifles that have inquiries made regarding conversion from .22lr to .22 magnum, and not all are suitable candidates.
 
If the .22 Mag reamer has a slightly larger pilot, it will not go into a 22 LR barrel.

Most likely it would require a .22 Mag reamer with a .22LR pilot. This would insure the chamber and throat are correct and it would most likely work fine.
