I have got to the age I have to have glasses to read, I can see from 5 ft. on out as good as ever. I can't see the caliber of a bullet without my glasses I shoot a 30/06 and a 280 rem. These bullets will not camber in the wrong gun but to the necked eye they look the same. What I do is I shoot brass hulls in the 30/06 and nickel hulls in the .280. I have always wanted to get into reloading one day so I always save my brass. I have a shoe box full of nickel .280 brass. A reloader told me you can not reload nickel brass. Can nickel brass not be reloaded? What is the problem with nickel brass?
