I am working on a Savage 24D Series M for a friend that came out of a pawn shop. Both barrels were misfiring. I changed out the main spring (Numrich Parts) and adjusted the plunger. Shotgun barrel works fine. On closer inspection of the 22barrel, firing pin, face of the frame at the rifle firing pin, and fired and unfired cartridges. I identified that the firing pin does not engage the rim of the cartridge enough to strike the primer powder. It only hits the rim enough to create a scar down the side of the casing. Firing pin extends just as far as on another Savage 24 I campared it to. (Also ordered a firing pin from numrich but they have the wrong listing for the Savage 24D. I have Numrich Catalog 21 which shows to different firing pins. One for just a Model 24 and a different one of other models of 24s. They list the same firing pin for everything.) The diameter of a 22LR is .275 mils and for a 22 Magnum .295 mils. The bluing on the barrel does not match the color of the frame. The barrel is much lighter in color. Is it possible that someone in the pass has swapped barrels and this frame is for a 22 Magnum? Can someone with a 22 Magnum/20 ga give me the measurement from the shotgun firing pin to the 22 Magnum firing pin. Thank You

I don't have any .22 mags, but here are some measurements on some .22/20s. Measurements are from the bottom of the shotgun pin to the top of the .22 pin. 24C Series N - 0.661"  24S-C - 0.662" (Yes, it is ugly and filthy, and I am a little embarrassed to post it before I fix it up, but I just got it today) It looks like the micrometer isn't open enough, but I'm just not holding it down tight for the picture. The measurement is accurate.  I think it's probably safe to guess that the rimfire frames are pretty much identical over several years, given a particular caliber combo? The barrels almost swap between the two, but the C barrel is too tight on the S-E frame and the S-E barrel doesn't lock up quite tight enough on the C frame. The S-C is an older (50s I assume) one with the barrels soldered the whole way down. The C is a newer ('74 I think) one with separate barrels. Hope that helps. |

Thanks for the measurement. The measurement on my gun is also .662 mils. I guess the barrel is the correct barrel. On viewing you pictures I can see that your the firing pin hits much deeper on the cartridge rim. How do I get my barrel to drop down a few mils deeper in the frame? The locking bolt assembly looks fine with hardly any wear marks. The problem on this gun has existed for a long time because of the imprint on the face of the frame. The shotgun shell firing pin hits the primer slightly below center. I just need the barrel to lock a few mils deeper in the frame. Any thoughts? Thanks

I just reworked my 24 V which had a little problem in the hinge area,regardless of caliber
they pretty much are the same as far as the method of how they were made in the hinge area.That said, I would take a good look at the pivot pin and see if it is worn or not.Then take
a look at the corresponding half diameter hole mating surface for wear. The distance between the half diameter hole mating surfaces and the face of the barrels control the space between the barrels and the face of the receiver,and with the face of the barrels being machined perpendicular to the bore keep the barrels from seating to deep in the receiver. The location
of the half diameter hole in the lug in would be one way to move the barrels up or down in the
correct plane. After all this long winded verbiage if the pin and hole are in good shape, I would
look at the firing as the culprit it may be worn out of tolerance,I had this happen on my old
Mauser and a new pin fixed the problem.
I hope this helps.

Thanks for the information. I will look at the hinge pin and half moon groove again. That might be an easy fix. I would like to eliminate the barrel spacing as the problem. I can't believe they would be put together wrong but I would like to make sure. Can LEAF or someone with a .22LR/20ga give me a measurement from the top of the 20ga chamber to the bottom of the 22LR chamber. I would like to ensure the barrel spacing is correct.

Sorry for taking so long to reply! Work, work, work... These measurements are made in the chamber, past the rim. They may be off +/- 0.005. They didn't seem to want to settle down. Here's the 24C Series N, 0.249":  Here's the 24S-C, 0.2455":  Close enough to be the same, I think. And my measure may be a little off. Maybe worth noting, though: My 24S-C does strike a shade low on the shotgun primers, but it has gone bang every time I've fired it so far (granted, that was only 6 rounds of .22, four slugs of two different weights, and two cheap 7 1/2 target loads, when I was test firing before I bought it). The lockup is tighter than a nun's knees (pardon the term). I don't really know what I am talking about, but I would clean the heck out of the place where the .22 firing pin sits and put some graphite lube in there, and look for evidence of dry-firing. Both my 24C and 24V/.30-30 like to misfire the rifle barrels when they get some fouling in there, and they both like to pierce shotgun primers, which is how the fouling gets back in there. It's pretty annoying, but I am not sure what to do about it...  |

Thanks again for the measurement. This gun measures .260 mils. Again when I look at the color of the barrel bluing compared to the frame and how much the firing pin is missing the catridge, I'm back to my original theory of "the barrel has been swapped" at some point in the gun's life. Savage would not have screwed it up that bad in manufacturing.

john54,
I think your assumption about switched barrels are correct. With the 24D Series M your talking late 1960's early 1970's and the switch from brazed barrels to separated barrels. The Savage parts catalogs do show a different firing pin for both the .22lr and .22mag. It's not that far off base to think the barrel sets and/or frames might have some dimensional differences too.
