Is there a safety problem with the Tubb2000?

[joesr]

Is there a safety problem with the Tubb2000 chambered in cartridges other than the 6XC?

I have heard that McMillen is no longer chambering in anything other than the 6XC and that the problem is that the design of the action does not support the web of the cases.

Has anyone else heard about this and what is the story?

I am not saying that there is an issue with the Tubb 2000. I'm simply asking about what I have heard.

Hi i doubt their would be a safety issue or it would not be safe to chamber the rifle in 6mmXC either. I would bet that they just want to sell more XC's and components like Brass. David Tubb must have a lot of money invested and trying to recoup it any way that is possible. Most who but the Tubb2000 will acept the chambering as it works perfectly for the XC type shooting and thats where they are shooting. They did make a tacticle version in 308 but i havent herad much about it for a while i would think it would have been to expensive for police departments and their are so many bolt actions and autos competing it was not worth ofering them any more. They seem to be awsome rifles but to expensive for my taste.

Bill,

Part of my last post was incorrect. The Tubb2000 is still being chambered in many calibers, just not the 6BR.

I have heard there was an issue with the 6BR and possibly it was the shooter's fault. However, the way the barrels are chambered makes a difference. You can chamber the rifle to support more of the side wall than what the original chambering does.

Also, I think you are off base about David Tubb. It is true that this is his business and he wants to make money from it. However, we all have or work for businesses that want to make money. There is no harm in that.

I don't believe that David is all about just selling the 6XC and it's components. If you ever get the chance to talk to him he does nothing but help you with what ever you need help with.

I don't believe that posting an unsupported opinion does any good of any of us. You are welcome to your opinion, however you need to have some basis in facks or experience to your argument.

I just got off the phone with the production manager at McMillan. He assures me there is no problem with the T2K and chambering it for the 6BR.

In fact they are still chambering in the 6BR.

I should have waited to post this until I had talked to McMillan. I didn't mean to spread any rumors.

Joe i was not in any way trying to say david tubb is biased and only wants to make money i should point out that one of the reasons the 6mm XC was designed was that 6mmBR's would not feed and eject 100% reliable fron the rifle because the case is to short one other reason the 243 was over looked is the case is just to long so the BR is not a prefered case for a repeater. A BR case is no more dangerous than any other 308 based case

What is the problem here? I posted a reply and it went into
the bitt bucket. Oh well what ever. I recientely blew a tubb 2 G 6XC case. Turnes out I did not completely clear the Sieco powder measurer of H335 form some 223 loads. The 2-3-4 gr acted as a Giant Primer and got the 43.5 gr VV N165 really going. Blew the extractor into 2 parts, complete through my leather shooting coat and into my shoulder. The suspossely unspported portion of the case left a fine ring around the solid case web. The extractor cut out in the T2K bolt failed. Left a very nice slot in the case. Those bemoning the unsupported portion of the case head in a T2K best suck up and remain quite. Ain't Gonna Happen! The extractor slot in the bolt head will fail first. Trust me on that! Got the brass fragments to the right of my eye to prove that. Hellave a bang and the 115 had to be going 4000 f/s. Later testing with the Mo case gauge showed no change in the brass from pre blast. I just have a problem with these jerks who mouth off about he unsupported portion of the brass in a T2K. Where are they comming from? -reid--

I own a Tubb T2k rifle chambered for the 6XC. I am extremely happy with it. I like it for many reasons. Accuracy is one. But the biggest is that it has taken the stock out of the accuracy equation. If I could have had a rifle like that 50 years ago I could have saved thousands of dollars in stocks over the years.

I have to chuckle at the thread starter who started with the scare phrase "Is there a safety problem with the T2K rifle?" Then two or three posts later he jumps on a guy who posts the opinion that possibly Tubb was in it for the money.

I can understand touting your own project/product, but to make unsubstantiated claims that a rifle is unsafe based on heresay is not very smart.

You are certainly entitled to your opinions, but the name calling relating to Mr. Hendricks is not in good form and just takes the quality of this forum down a notch.

rcw3, please reread the opening post on this thread. It reads innuendo, hints, rumors, heresay, etc. I could not find one truth in the whole post. This is what I think reduces the quality of the site. Honest opinions should be welcomed. But I think the hendricks post was in poor taste. You were right about the SR comment and I have removed it. However, if this hendricks is the person you believe he is, he would apologize to Mr. Tubb for starting the rumors. Carl L.

Carl L,

I was asking a question not making a statement.

In the past few days I have found out that:

1. McBros, the manufacture, does not believe there is any issue with the safety of the rifle, nor is there any issue with chambering it for 6BR.

2. Some people believe there is an issue with the amount of the case wall supported in the T2K chamber design.

I do not believe there is an issue with the rifle if it is loaded properly. Overloads or "hot" loads will create problems in any rifle.

I did not mean to create a "scare" or to create a perceived issue with the rifle. I was only asking if anyone else had heard about the issue.

I love my T2K and I would never shoot anything else at this point.

I hope you understand.

Joe Hendricks

PS...Thanks Mr. Whitley

Carl L,

You posted while I was typing my last reply.

My original post was based on a conversation I had with a customer of mine. It was the weekend and I could not get in touch with anyone involved with the T2K.

Should I have waited to post...probably.

After my conversations with many people would I have still posted....Yes.

I was simply asking for some input.

I apology to David if I jumped the gun on my original post. When I was on the phone with McMillan I told them I had posted on here and what I had said. I apologized to them at that point.

After talking with McBros I BELIEVE THERE IS NO SAFETY ISSUE WITH THE T2K AND THE 6BR!

However, let me tell you that I once blew up a 243 in a match. I broke my cheek bone in 4 places, punctured my sinuses and shattered the bone that supports my eye. This was my fault. I had a malfunction with my powder measure, that I should have caught. This was in a match with ammo prepared for match shooting.

Had the pieces of the action hit me 1" higher I would have lost my eye and probably died.

This is nothing with which to take lightly. Even rumor and even hear say the question was worth asking.

If there had been an issue and it had not been made public all of the shooters shooting this would be at risk.

I meant no harm to anyone.

JoeSr: Let us make peace. I now have a question though. I do not understand why the 6BR would pose a problem and the 6XC or the 243Win not. I would have thought if there was a pressure problem it would come from a case with greater volume, or I should say the larger chamber, which would leave less total metal in the first few inches of the barrel. With the case taper being very close on all three, I think bolt thrust should/would be about the same if loaded to the same pressure levels. Am I missing something here?

Well, Here we go.
The T2K offers almost as much support of the head as a Rem 700,within .010). The T2K sure feeds better.
All cases have different web thickness at the base of the brass.
6BR cases,which have limited capacity to begin with) have even less web thickness at the base, with lapua be less than Norma) simply stated- because it truly needs more powder capacity.

Then there are those individuals that try to load a 6BR to 6XC velocities. Having seen a couple of catastrophic case failures in 6BR with the T2K.
The T2K performed as designed,blow out the mag/extactor and vent the gas mostly downward). In both cases the shooter admitted that it was entirely their fault - all attributed to an over charged case.

I personally think the 6BR is not what you want if you intend to shoot Across the Course. If you are so inclined then load to the 6BR cartridge parameters.

A 6XC with current production brass will shoot a 115 gr bullet,bare) out of the barrel at over 3000fps in a 28" configuration - what more do you want?

If you desire more velocity - then shoot it out with a charge of dynamite,as one of the old hp shooters was quoted)- but dont be surprised if something fails.

The T2K is also offered in 300 WSM - I am shooting mine,hunting rifle configuration) with a 155 at 3500 fps. If this isnt a high pressure load then I dont know what is.

The T2K is probably the ONLY bolt action rifle that can be used with minumal eye protection,I would recommend that you wear glasses when you shoot it though). IF you have a catastrophic case failure in 6BR with a Rem or Win plan on learning to shoot with the offhand since you will be blind in your original shooting eye.

David,

I do apologize for starting this.

I apologized to McMillan on the phone.

I truly appreciate the information about the problems shooters experienced with the 6BR.

You are correct that if a shooter wants to shoot Across the Course,and I will add F Class and long range) the 6BR is not a good choice.

Your 6XC is a very good choice as it gives good velocity and great accuracy. No shooter will be dissatisfied with the choice of the 6XC.

I can speak from experience that a catastrophic case failure in a Winchester is very bad.

I think the Tubb2000 is the perfect rifle. I am about to receive my 2nd one. I have changed nothing on the rifle. There has never been any issues with loading, feeding or the feel of the rifle.

I think this is as perfect as a rifle can be for out sport.

I hope you can somewhat understand the line of questioning. Probably not. But I know the person who told me this information and I believed it to be true.

This is another life lesson learned.

Again I apologize and I appreciate your reply.

Humbly,

Joe Hendricks

Thanks. Cleared that up quite nicely. I had not thought about the web thickness issue.

My T2K, only been the possessor for two weeks, is everything that I had hoped it would be. 38.0/H4350 puts the 115DTAC across the Oehler 35P at 2879fps with an 16fps ES. Fast enough for my F class purposes. This load is giving me 1/4" to 5/16" three shot groups at 100 yards, and three and a half and five and one quarter inch groups at 600yds. I only fired two groups at 600yds. Then the wind came up. I formed my 6XC cases from 22/250 Norma brass. I was fireforming brass when I shot these groups, and still have about 63 rounds to fireform. That will give me 218 6XC cases. Extremely pleased. Strangely enough I did NOT get any mushrooms. Not even a hint of one. I am using the Tubb dies.
