I like brass better.
You will not get the life out of nickel that you do out of brass. After 3 or 4 reloads of nickel you will start getting split necks. Also if a nickel case gets damaged you might as well through it away. They are very hard to straighten back out.
Shoot carbon, but would like to dive into making my own wood. Have even attempted making my own arrowheads.
