case trimmer for 9.3x57

[rci2950]

I am new to reloading 9.3x57 and i was wondering if the Lee case trimmer for 8x57 (8mm mauser) would work? they are both x57 right?

Are the cases the same o.a.l. according to the reloading manual?
If so, the mouth will be a tad sloppy, but should work in a pinch.

both cases are 2.240" according to Handloader's Manual of Cartridge Conversions. Put a wrap of tape on the centralizer so it's not so sloppy.

BUT - I've never had to trim my 9.3x57 brass yet, even the cases with 5 firings are still in spec. This cartridge doesn't seem to grow much, unlike some others.
