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]

Enfield Eddystone Model of 1917 barrel threads are 1.125 with 10 SQ T.R.I., length of barrel threads is .800 inch also stated as 1.125"x10, square threads. Thanks, Peter.

Check out Frank deHaas two books Single Shot Rifles and Actions, 12 page of bbl specs., and Bolt Action Rifles, 10 pages of bbl specs. The NRA Gunsmithing guide has bbl shank specs for 106 different firearms.

[bearmn56]

Am looking for the shank dimensions and thread pitch of the Kimber 8400.

Large Martini
Small Martini
Remington Rolling Block

Might as well collect a full list and then make it into a "sticky" for all to share

[borrows123]

I don't think that it is possible..
But let me confirm this form my friend then I will reply you with the authentication....

[KCSO]

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

[corelokt]

Browning A-bolt
Old: 15/16 x 20
New: 1' x 32

[deltaenterprizes]

"Bolt Action Rifles" by Frank de Hass has a bunch of dimensioned diagrams in the back of the book.

[Artful]

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.

Very nicely done - This needs to be a sticky

[jkpq45]

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.

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?
