Problems with Tikka T3 Gas handling ??

Craig Henard

I just got through reading on another Forum that the Tikka T3 can give problems when there is a case rupture.
The way I read it was the case had ruptured and gasses had traveled down the left lug raceway and blew the shroud off and injured the shooter.


What was your point again?

Here's an oldie, but a goodie. Not sure exactly what you want me to "prove", other than I have a Tikka. Never had 5. Still waiting to hear what you learned at Tikka #5 that didn't matter with Tikka #1 thru #4.



There is a channel on the left. Ok, now I suppose you're going to tell me the Ruger T-3 is better than the Tikka T-3. Got it. Probably easier to use the "search" function as anything you could possibly say about either has already been said. And most likely more than a few times.

Now get back to cutting and pasting.

Be sure to site your source.

You didn't like my comment regarding Tikkler stray gas handling in the left raceway. Your pic shows there is nothing there to stop the gas, other than the magical shroud.

So what issue do you still have with my comment, as you proved my point?

Of course, there is this. Watch the Tikka at 23 seconds. There is no gas escaping backwards. Period.

Not sure where I said anything about your comments on gas handling nor which point I proved, other than there is a channel on the left side of the bolt.

You're barking at a mailbox.

Hmm the shroud did not fly off the back of the bolt like our "Expert GAS Handler" said it would. Anxiously awaiting his/her explanation of why it did not, perhapshe/she does not realize it but escaping gas whether it comes thru a .050 hole or a 3/8" hole is still bad for the shooter. He/She might also realize that the design of the bolt is of paramount importance ie how much the rear of the cartridge case is exposed.

Appears to be a place on either side of the cocking piece of the RAR where gas could fly out of . grin

That was a great video David. However, that was an obstructed barrel test, not a case-rupture test. The brass would still act as a gasket and seal the chamber. And remember that chamber pressures dropped by the time the bullet hit the obstruction compared to a partially lodged bullet followed by a case rupture.

A bullet was driven 10cm from the muzzle to act as an obstruction, the rifle clamped, then fired. It showed the strength of the barrel from bursting. Its also unclear if the bullet dislodged the obstruction as the rifles that did not burst recoiled backwards. Notice that the ones that busted didn't move in the vise.

Still an interesting test, but not representative of a ruptured case and gas handling.

See explanation above. You should really "think" before you "write"!

Too funny!

To Mrs. Oldelkhunter and 16Bore,

Since you wanted me to do the searching, snipping and pasting for you, I found a few posts regarding the magical shroud. I admit that this first one is lame, but better than the busted barrel test!

Don't trust the factory magical shroud, 16B? grin

Re: Problems with Tikka T3 Gas handling ??
It worked this time ,on my second post you can highlight the link then open the link to 24hourcampfire then open the other links once there.

OF course this is just internet talk but still !!
I just bought a Tikka T3 Superlight and like everything about it .
I hope there is no foundation for this but it sorta makes sense that in the event of a case rupture the gasses would travel down the left raceway and come back towards the shooter.??
Not saying I believe it but not saying I dont either.

I need some input and enlightenment on this subject guys.

Thanks
Craig

Re: Problems with Tikka T3 Gas handling ??
hi craig
im no expert on ruptured cases as i have never had one and dont want to.
tikka have the standard hole on left side of breech to release pressure and there is a hole just under bolt handle that would also release pressure at a guess.
the trick is to chase accuracy not velocity.
try not to worry bout the what if so much and go enjoy your rifle.
how is it shooting anyway? you settled on a factory load or a handload for it yet?
