Sir Dennis,
Good advice there for long brass life, minimal working of the brass.

Your rifle must be in SAAMI spec, eh ?
That allows for chamber length of 2.520", 20-thou longer than SAAMI max brass.
I still like to allow at least 10-thou for brass stretching on moderate loads.
I never trim shorter than 2.500" brass max if I can "heppit,"
and will let my brass grow to 2.505" before trimming back down to 2.500".
For low pressure loads I would be happy to let it go to 2.510" before trimming.

How I got a case head separation on initial fire-forming of Norma 404 Jeffery JRNE brass to 410/404 JRNE:
