I have been reloading for a few years but only bottle necked rifle cartridges....I am thinking of expanding I to 9mm, .40 and .45 pistol rounds. What's the down and dirty on the differences with prepping the brass and reloading that I need to be aware of? Obviously I know there are different powders for pistols but questions I have such as resizer die seating, are there case gauges for pistol brass, etc...?
