I have been loading for over 35 yrs and a gun smith for same time, and 20yrs ago was sold on nickel brass for rifles,
they are very nice and easy to clean, but what I started to notice before something went wrong was after 3 reloads
the cases cracked in my 270, Do not try to anneal the nickel brass, what will happen is the nickel separates from
the brass as it is super hard, and these flakes can migrate down your bore and when the next round goes off the
nickel will tear the rifling out. Some people have been amazed as why they had this happen and they kept there
guns clean, It never happened to me , as when I stared to have case splits and tried to anneal I noticed the nickel separate
and peal off, I was lucky but some times it does not peal until it is reloaded and fired. Nickel is good and safe for
extreme conditions, where you do not want your rounds to corroded in wet or humid env. but keep this in mind and monitor
your brass , also keep in mind that every time you size the brass you work harden it and it also will flake off as the two metals are
of diff hardness and constant working will cause the same or case splits which is just as bad .
Brass is still the best and used the most in serious target applications , Ie Lap brass and Norma
they have mastered metallurgy , there are good instruction vid on annealing brass. always monitor the web of the brass
where the brass meets the case head, it will erode after repeat loading esp. hot loads the brass actually flows inside the case
to the neck , that is why loaders trim both length brass wall thickness of the neck.
