Nickel brass is just more of a PITA then anything really. Its harder on stuff and it flakes off. Its really not high quality because no high quality manufacturer makes it, theres a reason for that...It will still produce 1/2-1 MOA accuracy with a pet load so its definately sufficient for general hunting purposes. For LR hunting or target shooting, I wouldn't use it.
With that said, I've used it over the years when it was all I had and it did OK. My dad just tossed his 100 that he bought for his 25-06, has 5-6 reloads on them and hes just now tossing them for peace of mind. I thought it looked "cool" back in the day when loaded with a combined technology ballistic silvertip or a barnes XLC. I do not buy it now, and only use it if I have to.
I run new brass through the sizer enough to round out the necks, then trim, chamfer inside/outside, and debur the flash hole.
