In a previous post I spoke about splitting Norma brass in 243 ( Norma Jaktmatch ammo) . After about 3 reloads ( 4 times fired) about 30 out of 100 cases are split. I plan to anneal the remaining 70 next week.
I also have some new ( once fired factory ammo) cases by Federal, Hornady, Winchester and S&B . Should I also anneal them straight away ? This to prevent them splitting or should I wait until I see the first signs od splitting?
