trimming

Can't throw the brass away. They are all sorted by head stamp (all of them not by lot though). It happens with a half a dozen different calibers. I do appreciate your input.. I think I'll just have to live with the .005" variation. I could go to something like the Lee trimmer that uses a shell holder that tightens the case head stamp against the shell holder to immobilize the case. Still not sure that the .005" variation makes any difference. I never have to trim my most accurate rifle's cases anyway (they haven't grown any so far), as they're Ackley's and the brass for these is all from the same lot. Of course I do check the length each time I load. Thanks again for the input/advice.
