Hi all, I've looked around the site and while I found some other threads referencing some of my questions, I couldn't find answers to them all. Please forgive me if I missed something. Here is the deal, I am comfortable loading shotshells and pistol rounds. However, I've never loaded rifle rounds. I am carrying M855s on duty, and want to load 62gr (though not necessarily M855s) for range time. I'm running them through an M&P15. I saw some recommendations on loading 55gr, but not 62s. Also, the thing that really is confusing to me, is what dies I'll need. I see collet and full size dies and having not reloaded these don't really understand what the differences are. I typically use Lee stuff, and see different rifle die sets and am not certain they are complete or which will be the best for my particular use. I would appreciate any help you might offer!
