Brass length?

[KenC]

When I trim I try for somewhere close to min as a rule.  So for 6Arc I'm set at 1.483.
I have multiple barrels which I keep close to each other in spec (I had a couple grendel barrels that stretched way too much so I got rid of them) so I size down 0.005.  That covers me for all of them.

You don't want to go out to the 1.500 b/c you need to allow the case to expand out during the firing a bit, then shrink back.

Geez. Exactly what my current set of reloads are set at. 1.483". I only have the one barrel, so I can actually let it lengthen a bit after the shoulder set back. Next set, after fire forming and set back, going to test the exact loads and see if there is any difference due to a longer neck which should provide slightly more neck tension. Who knows??
