Neck Sizing Only for 2 Different Bolt Rifles?

[TVC]

I have a lot of once fired brass out of a Remington 700 7mm Mag and recently purchased a Tikka T3 in 7mm Mag. The empty casings from the Remington fit easily (not difficulty closing the bolt etc...) in the Tikka. I do not have a full length 7mm mag sizing die however I do have a neck sizing die. As the empty brass is fitting fine and it is another bolt gun would it be ok to only neck size the brass?

Thanks,

They will work in the T3 neck sized until they stretch and harden from repeated neck sizing and firing.
They will get tight.
Ultimately you will have to full length size them.


Update: They may not work in the original rifle once you fire them in the T3.

If they chamber, then neck size and carry on.

Awesome thanks, that's what I was hoping to hear!
