Remington Barrel Question


AzRednek

Recommended Posts

Nope!

 

Not enough there on a Remmy.

The only practical re-thread is to a small ring. (.98 ) OD thread.

 

I've seen a guy rethreading Remmies to large rings (1.1) but they don't have

any secondary shoulder.

 

On the Enfield the ONLY shoulder is what is called the 'secondary' on a Mauser.

 

If you could even get 2 or 3 Enfield pattern threads on a Remington barrel there

wouldn't be any shoulder to tighten it to.

 

The very best solution to your problem is for you to send those Enfield actions to

me. I'll know what to do with them, then you won't have to worry about them

any more.

 

See what a nice caring guy I am, always thinking of the other guy before myself.

Gosh Tinker, so nice of you to be so considerate. I have a pile of bills here I don't want to worry about either. I'll send them to you and all you have to do is enclose a check, lick the envelope and put a stamp on them. I'll just use a little bit Elmer's Glue and steel wool to build up the Remmy threads. THX!!

I believe Rem 700 threads are 1-1/6" x 16tpi which by my calcs would be 1.062

Sound like he's building spear guns to me. :(

Can a Remington take-off barrel be re-threaded to fit a US Enfield receiver? Just a mind project at the moment but I have two Enfields collecting dust and see deals on Remmy barrels occasionally.

 

AzRedneck, I've done one for a LR mauser using a threaded bushing in 270. So far it's holding up fine. I've also installed a Sako barrel on a P14 Enfield in 7 mag using a threaded bushing. I used the 7 mag last hunting season and took several head of game. It worked perfect.

 

I admit, it's not the preferred method, but, sometimes you have to make do with what you have.

1917 Enfields should have a larger shank than even most available blanks. Blanks are usually 1.25" and enfield barrels should be larger to create a good shoulder to bear on. I can't remember off the top of my head but around 1.35" or something like that.

Thx everybody for the advice. Saw a deal on an unfired Remmy 300 Ultra barrel. I really want to build something based on the 378 Weatherby. I have a mint P-14 bolt, a good stock and a Bold trigger. All I need is a barrel and the ambition to get it done. In case you're wondering, I have no possible use for a Weatherby cannon but for some strange reason I really want one.

So in the case of using a Remington barrel, you would start with an Enfield barrel shank then D&T for the Remington

to thread into?

 

I think that Sako uses a smaller OD thread pattern than Remington.

 

Would you be able to D&T an Enfiled barrel shank at 1&1/16"?

 

I don't know the minor diameter for an Enfield thread off the top of my head.

 

Tinker :unsure:

tinkerfive, the way I do it is make my own bushings. I drill the bushing and bore it out to .750 id then inside thread at 16 tpi. I then turn the barrel shank down to .800 and thread 16 tpi until I get a tight threaded fit of the bushing. Then I epoxy the bushing onto the barrel and tighten. After that sets up you can thread the outside of the bushing for whatever action you want.

 

It never occured to me to use a threaded barrel shank to make a bushing. I don't know why it wouldn't work.

So at the secondary shoulder location you have a .75 OD - .5 (approx) ID (the chamber on a magnum)

leaving a wall thickness of .125.

 

Wow!

 

There was a discussion a while back about making magnums on K. khale Turks where you had a .88 OD -.5

leaving a wall thickness of .19 at the secondary shoulder. No one though that was a good idea.

 

The opinion put forth at that time was that you wanted a .25 wall thickness.

 

Note that I'm using the threaded shank minor diameter as the OD at the shoulder.

 

You might want to check with Mike McCabe about this.

tinkerfive, I'm not recommending that anyone do what I do and as I stated before, it's not the preferred method. However, if you add up the wall thickness of the barrel and the bushing, you get the standard thickness of .3125 (the o.d. of an enfield is 1.125). Like I said before, it's a tight fitting bushing epoxied in place. It's not as if there is air surrounding the .125 wall thickness of the barrel. So far, I have run into no problems doing this.

 

I might add that this is not my invention. It's been done before.

The problem I see with adding the bushing diamter to the shank is that implicitly you are assuming 100% thread contact which is not the case.

Hi Z, actually I'm assuming 99% thread contact and the other 1% is epoxy :D . Really, I'm not trying to promote this practice. I just threw it out there because I've had success with it.

 

I don't have any hard evidence of this practice ever having caused a failure. I do, however, have examples (albeit few and doesn't prove anything) that it has worked.

 

It's always best to start out with a fresh, new barrel if you can afford one.

So, here's my warning. Do it at your own risk.

My only concern is that the margin of safety is greatly diminished. Obviously it works. It's just that there is less room for error. Remember too that I have to play it REAL safe, it's the world we live in. ;)

I'm glad that you have chimed in on this discussion.

 

I have no issue with Rojelio 's methodology, in fact I think that I may try the exact same idea

if I can thread the bushing to 1&1/16X16 and use the Remington threads as is.

 

What concerns me is that the barrel that is firing a magnum load is in actuality held on by a .75 shank.

 

I understand the 99 - 100% contact for the pressure.

 

Every other barrel is held on by a shank something closer to 1" .

 

I'm just worried that one day the damn thing might snap off at the shoulder.

 

I'd hate to have anything happen to Rojelio .

 

I just wish he hadn't turned the shank down so much.

 

I think that Winchester uses .98X16. If he'd have used that dimension, I'd worry less for his safety.

 

Am I needlessly worrying about Rojelio ?
