Well, you asked for our methods. I, for no
reason that I would suggest you follow, use
only three 'brands' of brass. Fed, Win, and
Starline. I am very careful to not pick up
any range brass. I keep it carefully sorted
by the number of times I have loaded it.
After a certain number of loadings ( differs
for the different calibers ) I reserve it
for the 'low power lead bullet' reloads. I
also toss it (leave it on the ground at the
range ) after the 10'th load.
