i really don't crimp at all -- I just remove the bell --
If you have bullet movement when feeding you may have to crimp a few thou, or use a slightly smaller diameter expander plug.
Lube is for the bore --helps prevent leading --
Your boolits are probably dry luber rather than a lube groove -- perfectly fine -
On closer exam of your photo, the boolit body is a bit proud and could affect headspace.
You will enjoy this new adventure --
I recommend a copy of lymans cast bullet handbook for your reading pleasure.
