Rifle barrel and action dimensions list, info needed.

[lar45]

Hi all, I've been compileing a list of many different rifles and the barrel shank dimensions. Thread size and shank length.
I'll post what I have below, but there are still a few holes. If anyone has info on them, I would appreciate it if you could post it here.
The thought behind the list is to see what takeoff barrels might be useful on different actions.
One thought is it looks like Ruger 77, No.1 and Win-70 barrels might fit the Mosin Nagant and MRC 1999. They are all 1x16 tpi. I don't know how long the shanks are though.

If you know of others that aren't on the list, you could post that also.
Thanks.

Hi Bug, got it and thanks. There was a bunch of info that I didn't have. I'll have to take some time and merge it into my list.

[McLintock]

I've been looking for a list like this for a long time, thanks for posting it. The Browning BPCR and maybe all the Browning 1885's, as quoted to me on the BPCR Board, are .935" outside diameter, shank length is .920" and the threads are 20 per inch with a standard 60 degree form. Very similar to the Winchester 1885 but for the 20 threads per inch instead of 16 per inch in the Winchester.

Were you aware that Frank de Hass' book "Bolt Action Rifles" contains this info in the back section? It covers all of the military and commercial actions reviewed by him in the book, including shank diameter, thread pitch and I believe headspace measurements and rebarreling techniques. :coffee:

[pintopete]

Mossburg MVP 223 is a small shank .875 28 tpi on barrel threads

[frankenfab]

Weatherby Vanguard
26mm X 1.5mm

S&W 1500, Mossberg 1500, Howa 1500 are probably the same.

[Casting Timmy]

Dunlap's book has a lot of barrel threads too.

[lmcollins]

The Howa and Weatherby Vanguard have 55 degree threads. I tore a Howa down just to check this out and verify it.

These rifles take a lot of torque to get them apart. I was told by someone at the then Howa importer that they are "spun" together. I didn't try to explore that info with him.

Thanks for the compliment, Artful. I've been trying to get into amateur gunsmithing and have gathered a few things linked in my previous post, some drawings of a checkmaker posted here before as well as the ANSI documents for chamber and cartridge dimensions of most calibers.

[B R Shooter]

On the Remington 700 drawing, the inner "corner" as shown is actually the chamber end. Don't bevel this much at all, because you are taking away the brass support at the web. I chamfer the big end, but at the chamber end I just use some 400 grit and polish it. You don't want a sharp edge, just polished.

[Bullshop]

Thanks to all this is great!!!!!
One more question about Mausers. On the milsurp Mausers and others like Interarms MK-X and FN are the threads Whitworth form? Are they inch threads? So I get this straight is the Whitworth form cut with a 55 degree tool angle with a radious tip? If yes then the tops and bottoms of the threads are radious?
I am trying to learn this because I may want to modify some LR barrels to SR thread to fit some SR Turk actions I have.

[FrankG]

They are 55deg whitworth but if you are careful when cutting threads ,fitting for snug fit to action 60 deg threads work just fine .

[Bullshop]

Radious tip cutter? What to gauge the radious to?

[Uncle Grinch]

This list and related notes seems to be really growing. I'd like to see this complied into a database or maybe an Excel document.

[ADfields]

Good thread, Google it popped up for another thread pitch and I saw Rossi 92. Not many work on the Rossi but I make 256wm barrels for them and work on them a lot so thought I’d pad the list.


Rossi 92
All threads are metric 60 degree, all other measurements of the guns are inch just like the Winchester it’s a clone of. Rossi has the cartage lifter detent cuts in the receiver wall where the original Winchesters have these cuts on an apron attached to the left guide rail. So other than the metric threads, different detent cuts, and bolt safety on newer ones Rossis are a direct clone of the early Winchesters.

Barrel thread is M19x1mm, very fine. So fine it's a booger to cut well on a lathe, it's like cutting a 3/4"-40tpi thread.


Winchester 92
.809x20 (same as the 94) and a cheap stock 13/16-20 tap works great to open/clean a receiver, (13/16-20 is .8125” major .0075” bigger diameter) when re-barreling even if using an .809-20 threaded barrel . . . You can just about turn the 13/16 tap in there with your fingers but not quite.

[doc1876]

I am going to save this until I get back to the house in two weeks, I have the sharps info...........I think it is 10tpi in a flat thread, but I can't remember for sure

[cowboybart]

Savage 99 pre 1 millon S/N = .896" OD, 12 TPI square threads. .930" of thread plus .125" trunnion. After 1 mil they went to V threads but I don't know the pitch.

Colt Light Rifle is 1", 16 TPI and a .890" or .870" shank (I forget)

M1 Garand = .968" x 10 TPI square

Ruger Blackhawk = .668" x 24 TPI

Mosin Nagant .980"x 14 TPI

Weatherby MK V = 1.061x 16 TPI shank length of .701" with only the middle .501" threaded. the .1" on the ends are a relief cut.

Jap Arisaka 99 1.050"x 16.93 TPI x .7 shank

Jap type 38 and 44 1.025" x 14 TPI x .708" shank

Marlin 336 .780"x 12 TPI square x .770" shank.

The trouble is, as with cartridges, reference books copy errors from one to another. The thread data for the Steyr (aka Mannlicher) M95, which I consider about the best of the straight-pull actions, is incorrect, or only correct in some examples. I have seen a couple of these dismantled, and the threads are about 1.06x12, just like the 6.5mm. Mannlichers and Mannlicher-Schoenauer. I have seen one well rebarrelled by turning down the rear surface of the threads in a barrel made for the M98 Mauser.

I wouldn't be surprised to find others. You should check your actual rifle before you lay out money on anything.

The difference between 55 and 60 degree threads isn't that important, as long as you screw them up really tight. (You wouldn't, for example, want that rifle put together as gently as benchresters often do.) The shape of the roots and crests is even less critical. American gunsmiths habitually cut and fit Mauser barrels with 60 degree threads, with no harm done.

The 1x14 thread on the Lee-Enfields is the same as the large Martini, and I wouldn't be surprised to find it on the Snider and/or the inch-measurement version of the FN SLR. The small Martini is 3/4 x 14. Both of these are 55 degree Whitworth threads, but special taps and dies, with the 60 degree American thread, do exist and can often be bought on eBay. With the large Martini I have seen a successful rebarrelling job done with these.

[Reg]

Don't forget thread form. I have DeHass' books if you want copies of the drawings.

Yes, thread form is very important. In this country we normally use a 60 degree V form, many others use the 55 degree V form. There are also square threads and a few that almost defy description. None of them are interchangeable.

What is the info for Savage model 340?

[KCSO]

Threads... US 60 degree threads are Radius v formed threads and the radius is either computed off of the pitch formula and just slightly rounded on the bottom, better less rounded than too rounded. I just copy the first thread tools I made years ago off the fromula's. Whitworth thread is a 55 degree straight V thread with slightly squared tops, when you cut a Witworth finish up by making a pass over the top of the threads with a sanding sponge. Square threads like the Enfield and the Marlins are real holding threads and are cut with a tool that looks like a mini parting tool. You will need a set of thread wires if you don't want to be backing off all the time to screw the action in and out. If I get the threads to screw in say 3/4 or better and they are still a little tight I quit there and lap them in to a finish fit with 400 grit compound. Go to YOU Tube and check out Mr Pete's machine tios for a good tutorial on threading. His best tip... buy some delrin plastic and practice with that first, especially on Square or Acme threads.

A 55* threading tool is easily ground, the 55* threading gauge is available from many machine tool suppliers, so why not use 55* as matter of craftsmanship. The NRA Gunsmthing Guide - Updated has many thread dimension illustrated, including most mentioned here, along with other 'stuff'. Used available on Amazon - about $20. Machinery's Handbook should have all the threading specs.

CZ527 .988x1.25 mm pitch.
CZ550 1.1x2.5mm pitch
These 550 barrels are tight as all get out.
Last one I did was a 416 Rigby that I rebarreled for a customer
To 338 Lapua. Had to sacrifice the 416 bbl with a relief cut
.003 in front of the reciever to relieve the tension and that barrel
Was STILL pretty tight. They must be torqued down by gorillas .

Norwegian Krag 12 TPI , square shoulder, LEFT hand. I just finished chasing this thread on a stainless barrel...on a lathe NOT made for this. I had to MAKE a 4th position counter gear to get the feed direction for left handed threads....this lathe has no thread dial so I could not disengage from the lead screw until I was done...AND this lathe has no brake and the spindle does not stop so much as wind down...SO, I had to put a ratchet on the leadscrew and drive it by hand under no power.

There was much wailing and gnashing of teeth but it's done.
