difference in trim length

[gpz750]

How much of a difference is .004-.005 going to make? I have a bunch of 2x fired brass from different sources. Some is 2.005 and some 2.010 after sizing. I would rather not trim it all to 2.005 unless need be. Is it going to make enough difference to need to keep the lots seperate?
TIA

I doubt you can shoot the difference, 99.9% of us can't, load them up and go, buy a Sinclair Chamber Length Gauge, it will tell you exactly what your rifles trim length is, warning it's pretty long.

Groups will increase .0135" for each 2 thou in 2x fired cases. Now, on once fired it's half that, on 3x it's twice as much.

Or not. ??
