I use Nickle plated R/P .338 Win Mag cases for hunting. I carry extra rounds in a leather cartridge holder. I have reloaded one box of 20 now on their 6th reloading, neck sized only. I have found that thoroughly cleaning the cases by tumbling and a wipe down with a rag, some graphite lube on the neck generally does the trick for me. I have experienced split necks, but generally after a full length sizing. I wont use a Nickle plated case for hunting after the second reload due to the possibility of a split neck causing a flyer.
I like using the plated cases. Their corrosion resistance is great in leather, I believe they feed easier, and they are easier to spot if you drop one. My hunting buddies razz me about my " high dollar cases", I just smile.....
