Nickel-plated brass is very hard, and difficult to resize
. The case necks will split and ....just send them all to me and let me deal with the problems!!
Actually, I use brass cases for my Encore 30'06, but use Nickeled '06 to make my 338-06. That way I can't mix them up. I do the same with 308 and 7-08. It's just a very easy way of not mixing, esp the '06 brass. The only thing I reall see as different is that after many resizes, the nickel strats to wear off the necks and shoulders. I read once that Nickel is supposedly thinner to allow for the plating.
I don't know if it's true. Never had a problem with it, and I shoot my 338-06, 7-08, and .357 maggie a lot!
