I don't think anyone said it yet, so I will. Take the bbl out of your gun. Insert a few factory rds into the chamber. Pop them in and out with your finger. Feel how they "click" in there, then easily fall out when you tip the bbl and let the rd fall? Also, look at how far into the chamber they go when you push them in. This is exactly how your reloads should work. If you're anything like me, your first attempts will: 1) not go in, 2) go WAY in, or 3) not fit in the mag., which they also must do
