Isn't it a crazy world?
Here, we have eight straight posts and nothing but horrible experiences with nickel-plated brass. And I have absolutely no doubt that all of these folks have vast experience.
Personally, I've fired AND handloaded tens of thousands of nickel-plated cases with total satisfaction. Both my .280 Ackley and my beloved .223 Ackley absolutely thrive on Winchester-brand nickel-plated cases.
Short case life? Nope, NEVER.
Scratched dies? Absolutely NOT.
Perhaps my great experience comes from actually cleaning my cases very carefully, both at the range and with a vibratory cleaner. I also use Redding TiN neck-sizing bushings in a Redding Type-S die and, of course, all of my chambers were cut with a Henriksen reamer.
I find that nickel-plated cases give exceptional life and feed like quicksilver. They also fireform easily to Ackley configuration ... something I would not have believed without actually seeing.
One difference; the nickel-plated necks "spring" back .001" more than regular brass necks, so I have to use a .244" TiN Redding neck bushing on nickle and a .245" bushing for brass.
Accuracy is the same, whether I use Winchester brass-brass or Winchester nickel and the case life is at least 15 loadings with the nickel until the primer pockets eventually wear out or expand beyond that which is acceptable.
Soooo, I guess this leaves us with experienced folks on both sides of the equation. The reader is left to find out the truth by himself.
Personally, I'll be shooting "Lone Ranger" nickel-plated cases until I die.
