Try it with and without crimping. First time you try it without, load both rounds, fire one, then check the unfired round's OAL. Chamber tolerances can vary enough that crimping may very well matter. I don't think there are absolutes when it comes to doubles--and they are certainly too expensive to fiddle around with unless you control as many variables as possible.
