rifle casing size?

Is there a chart that shows o.d. on different casings. I am looking at 7mm mag,270 rem and 223 and 22/250.

Reloading manuals have proper size. try Lyman

Any decent reloading manual should have that info.

Google might get you there if you don't have a reloading manual.

I think SAAMI has chamber and cartridge drawings on their website.

You'd have to look up each cartridge individually, though.

.223: 0.378" at the rim

.22-250: 0.473" at the rim

.270: 0.473" at the rim

7mm RemMag: 0.532" at the rim (& belt)

Thanks guys for the info. E.Shell thank you for the xtra step.
