question for gunsmiths
I have what I believe to be an old Savage Model 3-B single shot .22 rifle. I say "Believe to be" because the rifle is marked Springfield (usual address, .22 S/L/LR ), and has no visible model number. Many people have suggested it was one of the Mdel 3 variations, of which thereare several. But w/o a visual reference it has taken over a year to finally narrow it down. I finally have found one (listed for sale on that other auction site) in which the action appears identical.
Numrich Arms doesn't list ANY parts for this model on their website. I undestand that SOME parts will interchange between the various Model 3 models. But there are differences as well. W/O knowing the interchangablity of this specific part, I'm wondering how difficult it would be for my local gunsmith to MAKE one.
Your advice appreciated.

Is there such a thing on a revolver as excessive clearance between the case head(the one in firing position) and the recoil shield? I'm assuming that they have to be close enough for the firing pin to dent the primer; but is there a standard gap, and if so, what, if any, would be the consequences of exceeding it?
Appreciate your expertise.0 -
On a centerfire revolver having excess headspace, providing the firing pin can properly indent the primer, there is no safety issue. Modern case brass has a solid web that cannot blow out as the old folded cases could, under an excess headspace condition.
Rimfire cases can blow out and spray fragments.
What gun are we talking about, how is the headspace being measured and what is the caliber?0 -
v35, headspace is an issue with a revolver. to much and you can have head separation, i have a three pownd coffee can full of .44 mag. brase fired in a revolver with ex. headspace and you can break most of them with your fingers. on the lower powered cals. (.38 special, ect.) in might not be so bad. but still not a good thing. 0 -
Brownell's sells a go/ no go gauge that you slide between the rear of the cylinder and the recoil shield. I believe the values for S&W revolvers is .060 (go) and .066 (no go). 0 -
Mike: I measure .008 with a feeler gauge between my .44 case heads and the recoil shield(don't have a device like j2k's example, and the feeler gauge only goes to .025 -so can't measure without an empty in a chamber). Do you know the measurement on the one you have?
The Lyman manual's diagram of the .44 has case rim thickness at .060 -measured with a caliper, mine only go .046 - .050(depending on the brand). That would put my total headspace at .054 - .058.0 -
i don't have the revolver that the brass was fired in so i cann't answer that, i would say that anything over .010" would be excessive (case head to recoil schield). and would check brass before reloading if it was even close to that. when headspacing rifles i use (assuming go gauge is .000) +.005 for no go and +.010 for field guage. 0 -

MW- I'm surprised to hear of case separations with a straight thick walled case. While there's no safety concern, I'd bring the headspace back to no more than .008" with a cylinder gap of about .005". I would also polish the chambers.
BWA- Your .008" headspace sounds OK if your cylinder gap is no more than .005"(measured at the same time).0 -
Thanks for the responses, gentlemen. 0
