Sounds like some light weight brass...how much did the cases weigh on their own?
I had some Hornady 270 brass that was 30grs lighter then the WinFedRem brass, straight to the trash with those lol.
Nosler lists water capacity, and are Norma made brass.
I measured the capacity of Lapua, S&B, and RWS brass and found them remarkably consistent at 76 grs water, filled to the top. I thought I'd measured Norma too, but for some reason it's not in my notes. The case weight of the Lapua was 188 grs average, S&B was 182 grs., and RWS 183 grs. Norma brass averaged 184 grs., and going by memory the capacity was the same or in the ballpark of the others.
There is a 9.3 mm-358 Norma Magnum floating around in Sweden. There is also a 9.3mm-338 Win Mag...
And we fooled around a 9.3-338 Lapua Magnum rifle, but didn't end up with very decisive loads so it will need more work.... but a 9.3-378 Weatherby would be much more....

You are right, Nosler water capacities for all their '06 based cartridges are showing about 10+grs light compared to other listings. They are actually light on many other cartridges as well, very few match up with other peoples findings. I wonder how they measure it to be so far off? I just checked a Norma 9.3 myself and the case weighed 185gr and held 75gr of H2O to the brim.

Other then this guy that measures it with the bullet seated first, then fills with water to determine capacity?

Dunno, maybe nosler measures that way too since the capacity does change with different bullet weights?

Yep - that is also the same way that John Barsness reports water capacity as well - they are reporting the available space for powder with the specified bullet, brass and C.O.L.
Here's my CZ 9.3X62 FS carbine.
Very handy outfit with low-powered scope.
Easily gets 286 gr bullets beyond 2500fps, 250s well past 2600, and shoots plenty flat enough for big game out to 300 yd. Ask me how I know.
Apparently this model is no longer being imported into Canada. Anyone know if this is true or not?

beauty of a rifle. cz usa is not bringing them in, but some dealers bring them in from czub so they can still be had.
And, is also the way capacity is measured when using the Powley Computer, which we utilized when calculating the first loads for the 9.3-300 Win that Garry had Bevan King build. They were very close to actual velocities measured over the Oehler when Doug got the rifle.

The reason why this measurement method is used usually is to provide a direction for use with other bullets, as per it gives the bullet shank seating depth (i.e. volume) so by seating another of similar weight you will get close or same pressure whatever the oal (only if the bullet doesn't crush into the lands, of course).
Most of us use a program to do so... Or you can go the extra mile calculating the volume of the bullet shank minus the total case content of water...
To do so, you take the measured volume of water (1grain / cubic inch in water [20°C] = 0.0039614 gr/in³) and you substract the volume of the bullet shank ( V = π x r² x h )

I've been shooting one for a year now, it's taken a black bear and a moose so far. I have it in a Custom Mauser and with the load I have now it puts three rounds into half an inch @ 100yds with 286 gr Partitions @ 2470 fps (chron), don't see me selling it for a long time if ever.
