To the best of my knowledge, I haven't handled a solid frame barrel that was removed from the receiver. What are the differences between take down ( with non-interrupted threads ) and solid frame barrels? Are they interchangeable?

Next, are there any differences in takedown vs. solid frame receivers of the same era?

Just that notch in the barrel and receiver for the latch on the forearm metal to fit into.

Can a gunsmith modify a solid frame barrel to be used on a takedown receiver and have takedown ability?

I've asked those questions a couple times over the last 20 years and I can't give you an answer. Where is CTW when you need him...missing since 10/12/22.

Thanks. I thought there were bigger differences but started looking closely at receivers today and only saw the notch as being different.

I don't see why not.

It would be a matter of dressing the barrel to draw up snug at top dead center with hand pressure, simultaneously bearing snugly at both places it needs to, then milling the key slot in both the receiver and barrel simultaneously taking care that the slot lines up perfectly with the lug on the forend iron when the iron is snapped into place. Not a terrible job, but not for the faint of heart either.

Then when all that is done, you get to start mixing and matching bolts to create good headspace because the likelihood of headspace being perfect with a bastard barrel is slim to none..

Solid vs TD... one the barrel screws in hand tight and the other takes more force. So, what dimension is different and on what part (barrel or receiver) and to what degree?

I have done it on a few solid frame barrels,making them fit a takedown receiver. the differance is in the barrels. Basically you are removing metal where the barrel meets the receiver,and where the chamber end butts up against the loading ramp area.I never actually measured the amount but it was minimal maybe.005. when you do this you are tightening the chamber toward the bolt face creating less headspace. i have only did this on rimmed cases and had no trouble closing the bolt on the barrels.Don

WOW.

I have a question about rimmed cartridges. Is it possible to resize these to a point that the firing pin doesn’t cause the primer to ignite?

Or does the rim hold the cartridge tight and in reality the firing pin is weak?

Thanks

Well put, Don. Whether or not headspace is effected enough to matter is dependent on how much one has to remove from the barrel to allow it to snug up hand tight. I had one that took a helacious amount of steel removal to achieve that (mainly due to the receiver face being atrociously out of square and needing to be trued before barrel surgery took place). After all that, headspace was frahundtsed and the mix-matching of bolts began. (Could've just deepened the chamber, a .303, but that would've meant renting/buying a reamer. By then I had a collection of bolts and it was relatively easy to select one that was short enough, thanks to the Savage protocol of using different length bolts at final assembly to mix-and-match for achieving tolerable headspace.)

John, the rim is the determining factor. Light strikes probably due to gunked up internals. That, or someone substituted a too short bolt sometime along the way without confirming headspace and the firing pin simply can't quite reach far enough.

I've wondered about that Savage protocol of mixing-and-matching bolts at final assembly in an effort to circumvent the need for working to tighter tolerances at all building stages. On the one hand it was an innovative approach (if a bit sloppy) and an effective means to increase production and reduce scrap. On the other hand it was certainly within the means of industry methods at the time to work to tight tolerances and achieve true precision which has the same end effect at the assembly points. Case in point: Springfield Armory. You can pick a M1903 bolt at random and stand a pretty good chance of it dropping it in a gun and having acceptable headspace. Don't try that with a Savage.

I’ve got a 99 takedown receiver that was originally chambered in 250/3000 and I have a .300 Savage barrel from a solid frame 99 receiver.

Neither are rimmed cartridges. Can the .300 Savage barrel be adapted by a specialist gunsmith?

Does the rotary magazine need to be swapped? Is a 250/3000 magazine incompatible with a .300 Savage cartridge?

Weak spring. I have seen them obviously compressed from being stored in the cocked position for a long, long time.

Pretty sure a real gunsmith could fit the 300 barrel to the 250 frame. the headspace would have to be checked with go-no-go gauges and the chamber might have to be cut deeper. the 250 rotor would have to have the neck area reworked to fit the 300 bullet. A 250 case would work in a 300 rotor but not reverse.I have only worked with the rimmed cases as its pretty easy. Don

Sure, and it doesn't take a specialist gunsmith, just someone who knows their way around a lathe and understands the dynamics involved. One way to find out if the rotor will feed - stick a handful in and work the lever. May well have to open the neck cradles on the rotor with a rat tail file or if you're daring, a Dremel. The cartridge guide may well prove a stumbling bolck too. Again, one way to find out...

Used to be in America there was always an old guy in town who had a decent set of machinist tools and the knowledge to use them, and loved taking on projects - sort of an outgrowth of the village smithy concept. Most all those old guys are gone now, and their tools have been converted into Hondas and refrigerators. For that matter, how many people do you know who embark on projects requiring the help of "that old guy" anymore? Few people tinker on stuff - we've become consumers of the first order, not makers of things. The country was built on the likes of our own Mike, Lightfoot, who saw a need/niche and filled it, people who could actually create stuff out of raw materials with their heads and hands.

So, am I correct that the threads on the barrel and receiver are the same on a solid and take down rifle? It is only the length that makes a difference?

I cannot echo that loud enough. As the folks who come here well know, our country today is nothing like the one we grew up in. The Greatest Generation style of living and values have evaporated. Most look down there nose at blue collar work. They would rather live in their parents basement and on the internet. If there is ever another World War it will all be gone. I have no confidence we could do it again.

Sigh...

Threads are the same. Nominal length of threads is the same. Only difference is in the interference/crush fit of the barrel/receiver interface requiring toque to achieve final indexing of the solid frame gun, versus the ability to index the barrel with hand pressure on a takedown.

Thanks guy's. Always something new to learn.

Gary, Not just the US either we had many skilled older gentleman who could turn their hand to anything, back in the 50's & 60's you took your tv set into a store for repairs same with washing machines, radio's etc try that now see how you get on

Johno

Both my parents went to automotive school prior to having me, so I grew up in a tinkering/fixit household. All my friends and my sweetheart are amazed at the things I've fixed or rebuilt from scratch.

I've been asked if there wasn't anything I couldn't fix, and with a sly smile my response was "WOMEN".

Even where I work my boss knows if something needs fixing and/or figuring out, he calls me.

And yes, it is a LOST ART!

Blitz

Yeah, fellas it's saddening, and like Lightfoot said, kind of scary.

I'm descended from a couple guys who were hands-on kinds of men. My Old Man told me once, after I had made a remark about his uncanny ability to repair stuff, "Sure, I can fix anything but a broken heart, so be careful."

I know a girl who not very long ago actually traded in her car on a new one because, get this, it was overdue for an oil change and she didn't want to have to deal with it.....

Maybe that kind of ever-present nonsense is what drives me deeper and deeper into the world of old things.

What any of this has to do with 99's I'm not certain, but I'll throw in my 2 cents.

We are becoming a specialized species that depend on each other for survival. Unlike our forefathers who were much more independent and self-sufficient.

That being said, old people have been whining and complaining about the younger generation as long as mankind's written and oral history. I'm trying not to fall into the same trap. I can just about guarantee you my great grandfather's generation thought my grandfather's generation was not going to amount to much. I can remember being a young whippersnapper and listening to old people complain endlessly about the government and the younger generation of sluts, hippies and pot heads (us).

Time marches on, things change, some for the better some for the worse. The human species will likely still be here in one form or another 1,000 years from now. It will be as different a civilization then as it was 1,000 years ago. And old people will still be complaining about that generation's government and the sluts and the hippies and the pot heads. None of it will matter to any of us or our 5x great grandchildren. I am going to enjoy what time I have left

If humans had been inbred for a few thousand years and had nuclear weapons 1000 years ago, we wouldn't be here now, IMO.

All we need to do is shut off the internet and electricity for a week, and 75% of the population will be dead.

Don't think for a minute that the Feds don't have this plan in their arsenal.

This thread took an unexpected turn

Hey Blitz that's the truth, until recently when I got sick we had a 100 year old house in the mountains in 2020 we got hit with the big bush fires we were stuck due to roads being cut and couldn't get out over a week. Both my wife and were raised in pretty poor financially upbringing in rural area believe me it stood us in good steed, no power which meant water either because we couldn't drive the pump.

For washing/bathing just fill the hose with water from stock trough and lay it on the ground to get heated by the sun this would not make great viewing on google earth lol, we had a river near by we got water and a small generator that kept the fridge running so we survived without a problem.

The old grey beards here reckoned if it couldn't be fixed with a piece 8 gauge fencing wire it was buggered

Johno

"There's nothing you can't fix with $700 and a .30-06."

I guess the thread took a turn when I lamented about about the dearth of neighborhood machinists, guys who could perform work on guns, such as making a barrel fit a 99, without having to seek out a specialized gunsmith.

Could be something as simple as having removed mandatory shop class and home-ec from adolescent schooling, and replacing it with God knows what. Instead of teaching kids how to use their hands to forge their world, we're teaching them to live virtually. Accelerated rush toward a utopian future (that may probably be inevitable), at a pace far faster than normal evolution would achieve.

Reliance on the whole, and not the individual, is a recent phenomenon. Our generation is the last one to hold to traditional values - we protested the war and explored libidinous attitudes, etc., but there was an underlying core of values that reflected those held by previous generations, we simply wove and adapted our own generational ideals based on that. That simply doesn't exist today in general and therein lies the disconnect. I'm in constant contact with college students- everything from hipsters, LGBTQ'ers, egg heads, freakozoids, and "normal kids" - and while by and large they're honest individuals, the common refrain I hear is that what's good for society in whole far outweighs individual rights. That's what scares me.

We have changed ….

Dad was a self-taught automotive mechanic in high school. Then was in charge of the motor pool while stationed in occupied Japan. Twice recognized as the best independent-shop mechanic in Dallas.

He wasn’t scared to try to build/fix anything. And I was fortunate to learn from him.

Together, we replaced all the windows his house; built a hip-roofed workshop complete with electricity and a concrete floor; replaced the water heater; converted the garage into living space; rebuilt the motor on my first car; built fences for my two houses; replaced the AC ductwork; built brick sidewalks and retaining walls.

My son, the lawyer, picks up the phone and makes a call.

I will admit that I am one of those guys; I have no machinist skills and fear that I would ruin a barrel, or worse yet - ruin a receiver. There are some things I have done - refinishing a stock (which should be redone) and honing the action of a pistol. But cutting a precise notch in the barrel threads, nope - I am a chicken.


There is so much I wanted to say in support of your thought - I wrote a lengthy response but decided to simply say “what you describe is communist China”

The communists sell you the line, "What's good for society as a whole outweighs individual rights" because it appeals to the philanthropist in all of us, but think about it. Nothing is better for a country in every way than an individuals rights to pursue life, liberty, and happiness. Individuals prosper, so does the state. Individuals do charitable works for those less fortunate.

What communists are doing is getting you to agree to give away your freedom and rights, period, end of sentence. BTW, ever notice that those at the top of communism become extremely rich? Coincidence? Subjects in communist countries ALWAYS live in abject poverty.

I am trained opposite of you guys.

I do surgery on farm animals.

I just gotta be clean, quick, and close.

It usually heals.

But i had a stud horse that had a square foot of hide ripped off his side by another stud. I had to be clean every day for about 45 days, slow patience and persistent for the hide to grow back without proud flesh.

The takedown barrels are physically interchangeable with the solid frame barrels for rifles produced in Utica and Chicopee Falls. That does not mean it is a cakewalk. The replacement barrel may not index correctly, and if it does index, it may not headspace correctly. Changing the forearm stud is easy if the screw is not damaged or rusty, and the stud will be in the right location if both barrels were later than S/N 90,000. I've done it, and that is all I remember about the changes.
