Not to be argumentative, but that’s not necessarily true. If you’re going to run a crimp die (tube fed mags and/or SHTF loads) you do want your cases all pretty close to the same length.Yes, straight wall pistol doesn’t need lube. I was thinking ahead. Same with trimming straight wall pistol.
Most mouth-headspacing rounds are going to get shorter with use, so there’s not much you can do besides artificially accelerate the shortening process... or not worry about it. Rimmed “cowboy” cartridges will get longer in time, and seemingly inconsistently (in my experience), so trimming is advisable.
