Wouldn't,,,or shouldn't,,the 6.5 Swedish round fail to chamber in any chamber with a standard '06 size base diameter (.471 (?)
I thought the Swedish round was a bit larger in diameter at the base than all those other common base rounds.
It's a guessing game at best this way. Perhaps it's a wildcat round of some sort too.
Way too many possibilitys
Get the cerrosafe or even do a quick cast with wax or epoxy while you wait if you have to order some.
That'll give you something to look at and give you an idea of the chamber shape, length, shoulder angle, ect.
Anything marked on the bottom of the bbl under the wood?
