Well it depends on how serioys you are about your equipment. I have used nickle plated brass for years for different loads. I generally use it more for weather than any other reason. One school holds that it will ruin your barrel by blasting tiny bits of the nickle down the tube which in turn gets imbedded in your barrel. Same thing is said about the dies. I personally do not own anything that I would ever notice this effect in. hunting rifles are capable of amazing accuracy but not on the lines of the BR group. As far as would I use them, I would and don't have any problems with them. They do require a little more attention with the lube as they will stick and stick good. They might be a little thicker than regular brass and require a slight reduction in load but it won't be noticeable in performance.
Good luck and have fun,
