I seem to remember having that conversation with my FFL and he told me that a complete lower would be transferred as a rifle..although he may have presumed it included a stock.
Or maybe I mis-remembered...could be that too.
It's a cost-conscious kit that is decent for the money. You don't have to spend a lot of money and should easily get a feel for whether or not reloading is for you.
It looks like it doesn't include dies. To start, you'll need a full body sizer die and a bullet seater (at least for .223). Crimper if you are firing semi-auto. I have not done pistol rounds but I understand it's supposed to be easier.
Digital caliper. Gotta be able to measure case lengths and COALs.
Looking at the shell holders you get with it, #4 will work with .223 rem, #19 for 9mm luger and .40 S&W, #2 for .45 ACP. So all the ones you need are covered in this kit.
