Wrong, the datasheet is common for all caps. Look carefully at the datasheet, they say "look at the product specifications for actual values".
Why don't -you- look more carefully at the datasheet? The link you posted is to a Mouser catalog page for Manufacturer Part #: DCMX632T450DG2B (in fact the p/n is in the URL), with a link to C-D's DCMX family datasheet. Page 3 of the datasheet explains that 632 means 6300 microfarads. The d/s lists 450 VDC caps up to 12000 uF and 500 VDC caps up to 9200 uF, but those extreme values might be made only when C-D gets a direct order -- they are not necessarily stocked by any industrial distributor.

I'm partial to using a stepup autotransformer off of mains for my coilgun projects. Its about the fastest and easiest charging option out there, as long as the goal is not for a battery operated gun.
I wouldn't be so fast to dismiss flash caps as a good bank, while they have their limitations, they are basically free and are designed for an application similar to coilgun use.
