Anyone know where I can get information on the case capacity (in grains) of various cartridges, including wildcats? Thanks!

Old Dog,

Any specific cartridges in mind?

I looked over the data on the Chuck Hawks link and for the most part it seems reasonably accurate. The -06, 300 Mags, 45-70, etc were all right where they should be.

The only ones I saw that weren't right were the 416 Rigby and 460 Weatherby magnum, both of which are about 6% high.

I have some wildcat data and many big bore cartridges data from measured cases.

Thanks for the info, guys! AC, I'd like the capacities of the 250 Savage AI and the 6.5-06 AI if you have them. Thanks!

I assembled a list alongside a calculator I use to estimate case volumes. For grins, I put it on the web. The list includes some archaic cartridges and a few wildcats, but it's most standard stuff. If you have the basic dimensions, the calculator can be used to estimate an "improved" case's capacity.

For accuracy, you should measure your cases, but this list should get you in the ballpark. According to the Clown, my numbers for the two big bores he mentions will be found to be a bit high (I don't own a rifle for either).

The water capacity for the 250 Savage Improved is 50 gr. Found the info on the web last month when i started a custom XP-100 project
