I'm fairly new to handguns and will be purchasing my first one next week (Sig P226 .40 cal) and I want to know what's a good round to shoot for targets. I noticed I can buy Fiochi FMJ's for around 15 dollars a box on Sportsman's guide by the bulk. However I don't want my gun to stovepipe. Also, which casings should I stay away from? Should I use brass, aluminum, or steel cased ammo?
