I have often wondered how far a Swede could be safely loaded to in a modern action like a Tikka or Sako or Zastava commercial Mauser. It seems that people are understandably reticent to put warmer loads for this old round into the public domain. The same might be said for the 7x57.

Couldn't you just start with 260 Rem loads and work gently up from there? With the slightly higher capacity of the Swede you shouldn't get into too much strife that way?
