I hope you guys are good with your metric conversions.
CIP specs for cartridge maximum dimensions for the 9.3x66Sako (first figure) vs 35 Whelen (2nd figure) are:
Rim 11.95mm vs 12.01mm
Case web 12.13mm vs 11.96mm
base to shoulder length: 55.80mm vs 49.48mm
Shoulder diameter: 11.43mm vs 11.20mm
Case length: 66mm vs 63.35mm
Junction cone: 34deg55min vs 35deg (addition of both shoulder angles)
Pressures (measured by transducer) are also listed as slightly higher in the 9.3 but I haven't worked out from the CIP spec sheets what Pmax, PK, PE are ... but the 9.3 is about 150bar higher in these 3.
Is it a bit clearer now that the 9.3x66 is not a 9.3Whelen?
Cheers...

Still reckon they're the same case?
