I reload since over 30 yrs, many calibers, from .243 up to 45/70 and many caliber in between and never, never annealing any brass
The majority of my reloads are near or max. load, now I resize the first time F.L. after only Neck size.
.243 up to 10 reloads to date and still fine
6.5x55 after 30 reloads I dispose of the brass
.270 win up to 7 reloads to date and still fine
7x57 and 7x64* after 25 reloads dispose of the brass
7mmRem Mag after 20 reloads dispose of the brass
.308, 30-06 and 8x57 after 25 reloads dispose of the brass
8x64* after 20 reloads dispose of the brass
30/30 and 32 spl. up to 10 reloads to date and still fine
.300 win mag after 20 reloads I dispose of the brass
.300WSM 20 reloads dispose of the brass
7.7 jap * 5 reloads and still fine
.303 Brith 5 reloads to date and fine
.8mmx338 Win** after 20 reloads dispose of the brass
.338Win Mag up to 16 reloads to date and fine
9.3x62 up to 8 reloads and fine
.375 HH at12 reloads...sold the rifle & cartridges
.45/70 4 reloads and perfect!
* fire form from 06 brass
** fire form from 7mmRem Mag or 338Win mag
When started reloading I only resize FL but I experience couple head separation around 12 or 14 reloads with 6.5x55, 06, .300 win mag and 7mmRem Mag, I change to neck size never happen again.
The limit of 20 or 25 reloads before disposing of the brass is due to the fact that after if I continue using them I notice that particulary on the Mag. the primer pockets are begining to enlarge and primer sit in loose, also over that limit I start noticing some neck hair cracks.
Probably with annealing I could get few more reloads but I do not feel that is worthed the time since have plenty of once fired brass.
