Help. Is cheap ammo bad for my gun? I just ordered a custom 1911 and I was looking to buy some bulk ammo on line. When I explained this to my gun smith he told me that I shouldn't shoot "Wolf" brand and others through a custom gun because it's not good for the gun. Is this guy lying to me? What type of FMJ ammo is the best to shoot for practice? I'm not worried about price if it wont hurt my gun. Something tells me ammo is ammo and my gun smith wants to make more money off of me. I don't know what to do. Any advice would be great. Thank you all so much.
