Does anyone know of a web-site that has a graph or something with pic's of the shell casings for different calibers? For instance, I'd like to see the difference b/t a 220 swift and a 223?

I've seen the display's that have the casings but they are limited to large calibers or mid-range Etc. I'd like to see this on a web-site that will span from .17 up to ??

Any suggestions would be appreciated.

Well, you can eyeball a cartridge board, or better yet, check out http://stevespages.com/page8d.htmand you can get the complete dimensions of any round that interests you as well as a line drawing of them for comparison......

Wow, I didn't realize there we're so many different cartridge sizes.Some of them are very close in caliber.

How am I ever going to afford a gun for each one?
