I don't reload so always trying to save a few bucks when it comes to range time. I recently acquired a super nice S/A Micro Compact .45 1911. Wally World has some decent prices (and even better in stock) Tulio (probably mis-spelled) FMJ ammo but it has steel rather than brass casing. I ALWAYS dis-assemble and clean my pistols after range time. Any issues with shooting these??
