I've been shooting all my life and in all that time my father only provided me with brass ammo. I'm at the age now where I'm buying and experimenting with different firearms and ammunitions. For the most part I buy brass FMJ & FMJHP. Now and again on sites like aimsurplus.com, ammoman.com, CheaperThanDirt, ect. I see some great deals. Like right now I found a great bulk deal on (MaxxTech 9mm Steel Case) but I'm unsure because it's not the brass I'm used to. I had one bad experience with Blazer aluminum case 9mm luger, but hell it could have just been a bad batch. What are your opinions and more importantly your experiences with different cases. Brass, Aluminum, Steel ???
