You can google any cartride and wikipedia will give you the rim size on the right side of the page. There you can compare deminsions to help determine the parts you want.

For SAAMI rifle cartridges, cartridge and chamber dimensions can be found here:

Should this information go on a sticky note?

Like the sticky at the top of the page of this section. It's titled "What Fits: Cartridge List (PDF version)"

It doesn't have the drawings, but it lists a bunch of the bolt head sizes. That's the focus of most of the questions.
