"...the TCA Encore can not keep tolerances and head space grows overtime..."

What is the design feature which allows/causes this?

"...especially with larger calibers like I was shooting (300 win mag)."

The word "especially" implies that this problem could arise with lesser cartridges. Have you an opinion about any cartridge to which this might apply?
 
Interesting, and very sorry about your injuries and economic losses past,current and future.

Without knowing the details, I suspect the 40% comparative negligence is at least partially due to a jury being unable to understand that handloading is not the boogeyman that manufacturers make it out to be.

Somewhat understandably, all manufacturers void warranties if handloads are used. But, I wonder if the OP's attorney's were able to demonstrate though post-failure analysis whether the failure would have occurred even with factory ammunition, because from what was stated a TC employee confirmed these failures occurred at the factory.

More details would certainly be appreciated, and has TC stopped production of this rifle, or made any changes?

I would always be suspect of a switch-barrel design at the price point of the Dimension. Other commercial offerings with that capability that I've seen (can't pull them from memory now) are priced many times higher. Where tolerances are in thousandths or less, everything needs to be as tight as a gnats behind.
 
While I agree that Encores (and other break-open design rifles) do have problems with head space on bottle-necked cartridges, I'm not convinced that this grows significantly with time. If you are a handloader, you can (and should) uses this known fact and resize your cases accordingly.
 
How does head space grow? If a break action, does the action loosen measurably causing the additional growth? Does the heavy cartridge cause some stretching or erosion of the chamber (just wondering).

What would be helpful, would be to see an abstract of the plaintiff's case, as presented by his attorney. I would also like to see the defendant's response in answering allegations that lead to the 40% culpability.
 
Headspace grows due to the battering and compression of the locking surfaces over time as the cartridge pushes against the breech block. This occurs with all cartridge guns and all cartridges, but in most cases it occurs so slowly that a rifle will last thousands of shots before excess headspace allows the cartridge case to become unsupported enough to burst, releasing high pressure gas and (usually) wrecking the gun and injuring the shooter.

Generally, in a high power rifle, the barrel will be shot out before headspace becomes excessive. The excess headspace will then be detected and corrected (if possible) in the process of replacing the barrel.

I don't have an Encore, and don't know enough about them to know why, or even whether, they are more subject than other rifles to headspace problems. The information simply says what the jury found, but there is no technical information on which to make an independent judgment.

To summarize and very very briefly in my opinion the big take away from my case was the TCA Encore can not keep tolerances and head space grows overtime, especially with larger calibers like I was shooting (300 win mag).

In my trial we had 3 guns with excessive head space.

My gun was out of spec.
A gun with 5 shots was out of spec.
A gun with no shots was out of spec.
How excessive?
How far out of spec?
How many firearms were checked, before those other two were cherry-picked for the trial?

What was the exact failure that you experienced?
How many reloads on the cases?
What type of inspection procedures did you use? (if any)


If you want us to believe, then you need to provide details.

We are not the ignorant masses, that accept phrases like "out of spec" to be the everlasting, incontestable, word of The Almighty. In the gun world, you must have data to support such statements.
 
In my limited experience, juries tend to believe the "expert" who is the better actor and can confuse the issue the most. Of course, many of us would not be deceived, but you can bet both sides will make sure that NRA members and gun knowledgeable people are kept off the jury. No one wants jurors who actually know something about guns involved in a trial, civil or criminal, that involves guns.

One of my favorite phrases used to be commonly used by state firearms experts - "bullet X is not inconsistent with having been fired from gun Y..." That means just about nothing, but most jurors will accept it as testimony that that bullet X was fired from gun Y.

To summarize and very very briefly in my opinion the big take away from my case was the TCA Encore can not keep tolerances and head space grows overtime, especially with larger calibers like I was shooting (300 win mag).

When you say "out of spec", what does that mean, specifically?

If the new gun was out of spec, a gun with 5 shots was out of spec and your gun with "100-300" rounds fired was out of spec, how does that support the claim that the headspace grows over time? From the 3 guns tested, it sounds like it might be possible to support the idea that the guns are not headspaced properly from the beginning but there doesn't seem to be any support for the idea that it changes over time.

In what way did the headspace problem contribute to a broken stock?
It blew apart...
It's probably reasonable to characterize a broken stock as a catastrophic failure although that's not what people generally think of when that term is used. It seems a bit extreme to state that a gun "blew apart" when the actuality is that the stock broke.

Is there damage to the gun that is not visible in the picture?

Also, you state that "The excessive headspace allows gasses to act on the plunger thus allowing the gun to open." yet in the picture the action is closed. Did someone close the action after the incident but before the picture was taken?
My face was permanently disfigured and sight in my right eye was lost forever.
Was this due to flying debris or from the scope hitting your face?

Out of curiosity, was the 40% responsibility on your part related to not wearing eye protection, due to the use of handloads, or was there some other factor?
 
While this incident involves the Encore, the Contender is of a similar design, albeit smaller, dimensionally.
I believe it was Mike Bellm that wrote an article/treatise about the Contender action "flexing" during firing. He stated that neck sizing a case for a Contender might work once or twice, but it would eventually expand (during the flexing) enough to prevent lockup of the action after being reloaded with neck sizing only. The headspaced case actually grows in length with repeated firings.
I also have personally witnessed a Contender action opening partially when firing, but I'm almost certain the owner had been tweaking with the internals, trying to lighten/smooth the action and trigger.

My point is that this type of action appears to have more flex in it than a bolt action does. I'm not sure that this played any part in this lawsuit, but that issue does exist.... at least in the smaller brother to the Encore.
 
I have seen a contender unlock after firing but that problem mostly went away when TC went from the one piece locking lug to the split locking lug. if the problem continued after the split lock was installed it was because the shooter was using reloads well above max. IHMSA shooters were always looking for the 100% ram load. that load doesn't and never has existed.

I should also add that the used of those loads in a contender usually resulted in bending the hinge pin and that meant sending the gun back to TC for repair
 
I'm still puzzled about what happened and how it was supported by the plaintiff's testimony (or his attorney & expert witness).

Since this was a verdict by a jury, I more inclined to believe the previous post about one side "being the better actor". I remember being on a jury for an arson case. Case was more than a week long, with the prosecution presenting expert witness after expert witness, explaining what caused the fire, when the fire was supposedly started and why they thought the defendant started the fire. Every bit incredulous supposition, but ignoring a dozen other reasons why the fire may have started. Trial by jury is verdict by who the jury believes.

since we know handloads were involved, how do we know that a single round was not double charged? How do we know that a distraction caused the plaintiff not only double charged but entered a totally different powder into the case?

Without technical details, I remain suspect. To the OP: You OWE us telling us exactly what happened, even if the error was completely on your part, with a handload, simply because if it happened once, it can happen again.
 
Regarding the 40% fault issue. It seems like a lot of people are getting hung up on that. I’m not trying to hide that at all. But it is pure speculation why the jury decided how they did. I posted all the information I have: the verdict. The jury didn’t write a paper summarizing their thoughts in the deliberation room.

I shot factory and reloads. When my gun came apart I was using reloads. My loads did not exceed SAAMI PSI for the 300 win mag. They were at max but not over.

I will not be posting for a few days. I’m going away with my wife and kids for Memorial Day weekend. I should be back in front of my computer Wednesday. I'll try to answer all the questions when I get back.... sorry!

Thanks,

Brian Ward

As an expert witness (court certified in firearms, ballistics and failure analysis) one thing that the general population may not realize is the burden of proof for a criminal trial is VERY different than for a civil trial.

For criminal, it is "beyond a reasonable doubt". In essence, as an expert, I have to be able to eliminate all other potentials except one, at least as it relates to physical laws. Even for Civil cases, this is what I attempt to do, however many other "experts" make a good living on playing on the civil burden of proof being pretty squishy.

For civil, it is "more likely than not." As an expert, if 3 or 4 theories exist, an opinion that one theory is at least 51% most likely allows the expert to basically state it is fact. This is often misleading and confusing to jurors, litigants and even courts at times.

In this case, IMHO, the plaintiff expert would have had to use physical evidence to connect the potential of the firearm igniting the primer when the action was unlocked...if the claimed defect was catastrophic. That is extremely difficult to prove.

A loose buttstock can fracture even if the action is locked, and result in injury...this would be considered misuse of the product, but one that the manufacturer should be aware of and guard or warn against. I do not see this addressed in the T/C Encore manual (current).

An improperly sized case, debris or fouled chamber, wear in the locking mechanism (or hinge pin) can be mechanical reasons why this type of firearms could "potentially" fire without being locked, however, the more prevalent cause is just not ensuring the action is locked.

However, the manual never warns of these conditions nor the potential that the firearm can possibly fire when not fully locked. The closest the manual gets to a warning (current version) is this:

WARNING: IF YOUR FIREARM GIVES ANY INDICATION THAT IT IS NOT PERFORMING PROPERLY OR THE OPERATION OF YOUR FIREARM HAS CHANGED “THE WAY IT FEELS OR SOUNDS”, STOP FIRING. MAKE SURE THE FIREARM IS POINTED IN A SAFE DIRECTION, UNLOAD THE FIREARM AND HAVE IT INSPECTED BY A FACTORY TECHNICIAN. CALL THOMPSON/CENTER CUSTOMER SERVICE.

Under the criteria for "warnings" which is typically based upon ANSI Z535, this is not a warning. The warning relies on an assumption related to the perception of a "change" in operation which, as an expert, I would argue is beyond the knowledge of the common user.

As for the 40%, Brian Ward ignored the written warning in the manual to wear safety glasses when shooting, however, the connection to the actual injuries does not appear to have been supported thoroughly, so the jury may have assigned the contributory negligence for another reason. If the defense was able to convince the jury that Mr. Ward was a "sophisticated" user, then the lack of warnings argument is diminished and Mr. Ward could then be assigned contributory negligence.

Also, the jury questionnaire does not assert that T/C was negligent. That typically goes to the notion of "notice." In essence, it "may" illustrate that the jury did not believe T/C had prior notice of the specific reasons that they decided in the plaintiff's favor.

I am not attempting to tell anyone that the jury verdict was correct or not, nor that Mr. Ward was correct or not. My only intent is to provide the readers of this thread with a little bit of insight into how cases like this may go in legal proceedings. I have worked both for and against large manufacturers on a multitude of firearms related failures and accidents and in the large majority of cases, user error was the cause. In most of those, one of more of the 4 laws of gun safety AND a direct violation of proper warnings in the user manual occurred.

At this point, the information I have seen on this specific case so far is a toss up at best. There are several unanswered questions and frankly, while I will dig a little deeper for my own education, since I am qualified and do work on these types of cases, I won't write my conclusions that would support one side or another since there is an appeal.
 
Go a step further Snyper: on the handload forum I started a thread about tolerances in powder measures and I was surprised that +.2/-.2 grain seems to be typical for powder measures. Add into the mix the tolerance range of scales/balances and the stack-up results could have a load put together at the max actually well beyond max.

But again, the OP has not given us all of the facts. Regardless, if anything, this reinforces to me, the need to stay below max for my handloads. Additionally, it was alluded in one of the posts that the injury was to the OP's eyes, again showing the need for safety eyewear.

I am not doubting the OP's belief, but more of "Murphy's Law" in that if something can go wrong, it probably will, and precautions should be taken.
 
I can't understand how a broken stock constitutes an "out of speck gun blow up".
I experienced an actual "rifle disintegration" with life threatening results. Pieces were scattered over 100'. The barrel was projected approximately 30'.
