Thanks again, LRRPF52. That's real good having an explanation like that.
Flyrod, yes that was my thinking too. The older A1/L461 action was chambered in 222, 223, 22PPC and 6mmPPC (although few of the PPC were ever sold I believe). The manual says it was rated at 60,000 psi. But the new 85 extra short (XS) action only seems to have been in chambered in 223 so far. Sako have a nicely scaled range of actions, which are a bit easier for me to understand than the great range of bolt actions available from American gunmakers. I'm convinced by your idea on the 284 as well, generating a thrust from the widest part of the case not just the smaller rebated base. I think the Beowulf is rebated like this too but the rated pressure is way down to 33000 psi (from wikipedia) as the bolt strength in AR is the limitation. I wonder if it could be increased in a string bolt like say the Howa mini ?
