One more time:
There's a lot of room between getting sloppy, not giving a shit and 1000 yard rmatch rifle brass prep.
One more time it matters. It all does.
Try it at 300 you probably will see.
I shoot at 300 quite often. On the target I posted earlier I made notes to include the head to ogive length including a Sinclair nut comparator. The rifle I was shooting that day likes its bullets seated a bit shorter than some of my other 308s. I know this because I tested for it.
I'm not taking the extreme position of "nothing matters for hunting rifles".
