I am new at this, and I've just bought a new XD-M 9mm that I love, and I want to use the right ammo in it. The problem is I don't know much about ammo except that it is expensive. My immediate need is for good target ammo. Everyone has their favorites, but is there a publication where someone fired a lot of different ammo and objectively evaluated it? Does the same ammo fire differently in different guns? Can you point me to a link on the web that has researched this?
