I have done a lot of reading about .45 ACP headspace and case dimensions for 45 brass and I am left wondering as my brass collection which includes Winchester, which runs short (.891-2) and gets shorter quickly, to RWS, Federal, Speer, Fiocchi, and PMC (which seems to be longer on average, .894+). My Lee case lenght guage seem sto cut the cases too short and I have takien this issue up with Lee. I guess I could find a very thin washer to shim it, but so far haven't found any washers in the .003-4 range.
1- Why the brass gets shorter with use?
2- Does trimimng just enough to square the case mouth help in any way?
3- Who makes the most consistent size brass with the new bras being right at .895-.897/8 right out of the box. .898+ would be great so you could square the case mouth without losing any length.

Any thoughts would be appreciated, Thanks
