I was reloading 340 weatherby and I had Some difficulties initially, for 3-4 brass, i kind put the neck downside and i lost Some angle. Is it safe to shoot it?hopefully the problem was solved after couple but for the first? I CAN see one is completely lost in. What do you think?

Why take a chance and risk injury? I am no metallurgical engineer, but if that case has been deformed so badly that the metal has started to lose its integrity, this is an accident waiting to happen.

Even if it shoots, without accident, it will shoot lousy, because the case volume and COAL are different.

Again, why bother? Pull the bullet and throw the case away.
 
Looks to me like the bullet that you are seating has no cannelure ? I have seen this happen when the seating die is set far enough back so as to "crimp" the slug in place , and with nowhere for the brass to go it just pushes the whole issue back . I agree with the other posts ! The round (may) chamber and discharge .However .340 weatherby is a fairly high energy cartrige and the chamber pressure developed 51 000 - 53 500 cup will find it's way out one way or another . The best you can hope for is to re-form your brass ! and worst case could be much worse , I would pull the bullet and salvage the componants .
 
Out of curiosity, did you lube the inside of the case necks? I had something like that happen years ago with .303 and cured it with the lube brush.
 
Yeah, David L, it's yet another boring step, and most of the time it isn't necessary, but sometimes the bullet being forced down into the neck binds. The strength of the neck is less than that of the friction between neck and bullet and the neck crumples.
 
Neck lube aside, the number one problems that causes case collapses like that, is over crimping, or trying to crimp a case with no crimp groove using a standard die.
Do check the diameter of your bullets.

As to firing it.
IMO, it's likely safe to do so, however, you should be aware that problems could arise.
It's one of those you're on your own scenarios.
Remember you are dealing with a high pressure cartridge.
I've fired worse, but always with low pressure cartridges.
