Re: Caliber Choice?????? I need your wisdom please!!!!
Actually, I just went to the Hodgdon site, chose a bullet weight and a powder brand, and compared max loads.
While this may not be a valid comparison of actual capacities, I think it could be a valid comparison of <span style="font-style: italic">usable</span> capacities, and IMHO, that's probably a more realistic comparison in the longer run.
I try to stay away from H2O and other media when doing case capacity measurements. IMHO, the only medium that's worth a dang is the actual powder I'd be using in the long run; and that's how I do my case capacity measurements, by overfilling each individual case using a drop tube, then weighing the results. This gives a capacity measurement that has an actual bearing on load density percentages. Point of fact, I don't really do a whole lot of such comparisons anymore, in keeping with my more recent minimalist handloading practices.
When actual cases and powders are not present, published data can also be put to <span style="font-style: italic">reasonably</span> effective use.
On that basis, I'm actually moderately annoyed that there's no .30cal case with a .473" base diameter whose case capacity fits anywhere between the .30 Kurz and the .300 Savage. That would, IMHO, make a pretty effective chambering for FV200. Someday, hopefully soon, I'm going to want to get a .30cal heavy barrel blank I'm holding chambered for such a round, and right now, looks like I'm going to have to settle for the .300 Savage. Actually, with commercial brass and dies, etc. reasonably available, maybe it's not such a terrible choice after all.
