"if "not much" is your accuracy standard,
then don't trim to uniform length.
(or do any of the other brass prep steps)"
Then again, maybe it depends on our ability to discriminate between what's meaningful and what isn't. It seems new guys major on trivials, maybe because that's what they can wrap their minds around?
Case prep can only go so far. Anyone thinking a zero tolerance for case length is a rational "accuracy standard" is gonna go nuts trying to figger out how to match primers in precise brissance batches or how to determine actual bullet grip from different cases vs. so-called "neck tension" and counting powder out by kernals.
More reasonable folk use a bit of common sense and recognise that a few thou difference in case trim length is meaningless in the larger picture of fine accuracy from high capacity (long range) cartridges. Learn to properly develop an accurate load and most folk will be amazed at how tolerant it will be about the trivials new guys like to agonize over; like high precision case length.
