Model 24 Barrel Compatibility

Short answer probably they will not interchange without proper fitting. That said, I have an older Savage 24 (Stevens 22-410)which I have found several extra barrel sets for that fit properly (and a few that didn't). It's really a matter of luck. If possible always try for proper fit before making the purchase.

Actually you can swap barrels without any fitting.I've had several 24 in rimfire that I've switched,but you have to make sure that the barrels are of similar type extractors.There are 2 styles of extractors--we're talking about the shot gun barrel extractor. One style is the "flat" style and the other is the "round" style.The shapes we're referring to reflect the shape of the opening the extractor fits into under the shot gun barrel breech--either a round hole or a flat slot.Rimfire barrel sets in 20ga and 410 ga with flat extractors will generally drop right in.Round extraxtor barrels will NOT fit a flat extractor reciever and vice versa. Round extractor 20ga will not swap with round extracor 410ga.
Centerfire guns is a whole different story.All 24V (B,C,D) guns interchange ( 222,223,30-30,22 hornet and 357 mag/max) EXCEPT for the 24V-A in 222--the upper firing pin does not line up correctly.In 24F 12ga all the barrels interchange except the 17HMR set.Finally the 2400 combo series all interchange and can use barrels for the 330 series over/under sets as well.

Gsarge: Sorry, but all my extra barrel sets are presently being used. The sets that didn't fit have been passed on. In my experience all Stevens 22-410/Savage 24 barrel sets do not interchange (I've checked many many of them, the basic/early 22/410 and 22/20ga). Just because you can mount a barrel set, with whatever extractor, does not mean it is a fit. The locking bolt must engage the barrel under lug properly. In many I've tested this will not happen without some proper fitting and some never will fit. JMHO

Two items
First the 410/410 barrel set I have will fit in the 24 V -B,C,D recievers I haven't tried it in the 24V-A.

Second I'm pretty sure if you have a flat extractor style you will not be able to use a round style,if the barrel set fits perfectly then I have test fired the gun (using a primered shell only) to make sure the firing pins hit correctly. if it doesn't lock in I have taken my jewelers files to adjust the fit--there are 2 places to do the adjustment--the "v" notch the locking bolt engages (this is the area to work on if the barrel closes completly but wont lock) or the "half moon" at the front of the barrel lug where it rotates on the reciever front post--this is the adjustment point for barrels that hit the reciever face by the firing pins.I worked in small increments to make the adjustment--it wasnt really a big deal

OK, so I have now successfully installed another barrel set on my receiver and it works like a charm. A .22WMR/20gauge showed up on eBay and after confirming that it had a flat-style extractor, I made the purchase. The bores were in good shape and the exterior had some surface rust, but no serious pitting. Anyway, I got the barrel for $165.00 (probably a little high), but shipping was free, plus the guy threw in a buttstock that had some cracking for free too. The barrel slid right into the receiver nicely, but would not quite close, so I took bigkelly's advice and used a dremel with a barrel-shaped fine grinding bit to incrementally work the half-moon on the barrel lug. After three gentle grindings, it seated and locked into place perfectly. I put 20+ rounds of .22WMR and 5 rounds of 2-3/4" 20-gauge target loads through it without a hitch and it sighted in very nicely. Then, I took it back home and stripped the barrel using 00 and 0000 steel wool and Hoppe's #9 solvent. That did a great job, but also took off what little bluing that was still there. Now, since I really didn't want to put any more money into this project, I decided to do something that might disturb some of you, but please keep in mind that my plan all along was to make a serviceable gun out of what parts I had left over from a 'ruined' gun at minimal cost. I used Birchwood Casey Gun Scrubber to remove all the oil and residue, then tack-clothed it and applied two coats of Rustoleum rust-stop primer followed by three coats of Rustoleum oil/solvent/heat resistant flat black grill paint. Finally, I glued and clamped the cracks on the free buttstock which were unfortunately on the forks that mate with the receiver, so I also reinforced them with some JB Wood Weld. My original forestock has long-since been painted flat black, so that made it an easy decision to do the same with the buttstock. Finally, I put three coats of black satin exterior latex on it along with an old rubber buttplate. Thanks again to everyone for their input and especially to bigkelly for making this a success! I posted photos of the finished project to the forum here:  savage24forum.boards.net/thread/763/bringing-old-24-back-life

Thanks captcapsize! I couldn't find a way to post the photos to the original comment, so I posted them in the 'photos' section of the forum and put the link at the bottom of the comment. Likewise I posted a link to these comments with the photos so folks could read the story. I don't think its working too well or that the re-build is being well received because yours is the only comment I've received here and there has been none to the photos. Oh well, no problem here - I'm quite happy with the outcome!

OK, this is weird. I noticed a spelling error after posting the comment above and clicked 'edit'.  Once I went into the edit mode, the 'add attachments' button was clearly visible.  So, I went back to the original full story comment and clicked 'edit' and posted them there.

Here's a couple close-up photos of the top and right side that I couldn't post above, since the limit was '3'.
