What was oushed for was the removal of the minimum case length...... ideally, the scottish logic of energy level... but remember, this is Victoria!!
This is an interesting round, a super hot 'little' 6.5...not an original concept (honestly, originality ran out decades ago in the industry, how many times can you reinvent the wheel....
Ruger.
I reckon one of the best newish chamberings was the 375, attains H&H energy in a standard length round (and action) they by-passed the belted short magnums (win mag type) so as to make use of the full diameter of the case while retaining standard magnum (H&H) rim diameter. Fatter than win mags/more case vol...
Nosler have replicated this thinking, with one difference; they pumped out the case (on the mag rim) to grap a bit more volume, slightly fatter than Mr.Ruger. creating a slightly rebated rim as well (pros/cons)...
This will probably be more appealing to the wildcatters... I see necking up into a 30cal, more oomph than the winmag, not RUM level but in the standard length, maybe a 375 for the slight plus on the ruger?? 338, is probably already done... would be interesting to see how many XXX/26Nosler reamers are out..
Case wall slope/taper is, for the record, similar to 308win
