I have a MEC junior for shotgun shell's, been using it for 40 years. Its simple and reliable, and its not so complicated that I have introduced my grand kids to reloading. What ever reloading press you get you need to get a selection of powder bushing's and different shot charge bushing's. If you haven't reloaded before then make sure and get a good reloading manual, or reference the online data center's. Here are some powder supplier's with reloading reference.

Also make sure and do a search on this forum for reloading tips.
Good luck and have fun.
