This is an option for you FM. It's a little pricey, but they don't make them for 10 gauge anymore. It might be easier than finding 10 gauge blanks. You can get creative with your loads. Every thing you need accept for hulls, primers, wads, and powder is in the box.
When I got into reloading, I made some very accurate .270 Winchester loads with the lee loader. It is a very easy process.
