Can U figure this one out?

Rifle: Rem. 700 - 338 mag.
Problem - Once fired factory brass will not fit back into chamber and be able to close the bolt!

I was helping a friend trying to figure out this problem. I checked headspace and it was good. I resized the casing down as far as the die could go - still not work! I thought maybe a small base die might help, nope.

I did find out what the problem was after I took it to our local gun shop.

So lets see if anyone here can find the answer. I will come back later and see if anyone got the answer.

Every swinging richard should own a Hornady Chamber length tool.
There is one for semis and one for bolts. You can use the semi one in some bolts, but not the other way around.
You get a special case that is your caliber. That case is trimmed to SAMMI spec.
It will fit into your chamber. See how much longer you necks are on the once fired.
Trim baby, trim them cases down.

Remember you have over all case length & Over all round length.
Both must be within spec of your chamber.
