You know bumping a topic after 2 minutes doesn't help in any way at all right?
As for your problem, it's not. The last 4 or 5 BB's in a mag will NEVER load. It's how the hop up unit and mag interface. There's a tube that connects the mag to the main hop up chamber and if the BB doesn't get in there it won't hold.
As for the mag wobble problem, that's also normal. Shouldn't have too much play but some play in the mag is normal. Worst comes to worst just tape it and add some layers to make it tighter in the magwell.
