Nickle plated or brass

[sauer06]

I just reloaded some brand new 243 nickle plated cases with some Hornady and seira bullets andI noticed something that I have never seen while reloading brass cases ( I have never reloaded new nickle plated cases) and it seems that the hard nickle does not let the soft copper plated bullet inside with out leaving a lot of metal shavings, I have of course removed them, have tried to expand the neck of the case using my 243 RCBS die but it still happens. And another question, why are these cases harder to chamber? Is this nickle plated stuff that much stronger?

think about it, the nickel is springing back more making your cases larger with the same setting of the die.
as the brass flexes inside the nickel, if the nickel starts to flake off, those flakes are hard enough to scratch your dies and your rifles chamber. I saw it while working on a load for my 25 wssm, I will not reload nickel cases over about 2 times. and won't buy new nickel brass for that limited amount of use.

I like nickel plated cases for ammo that will not be fired and reloaded a great number of times, as it may flake. Use brass cases for ammo that you will fire and reload often. Also nickel cases are good for cartridges that you may load with black powder, as they are easier to wash clean after firing.....
