I am using hornady's digital scale. I'll get a picture of the bullet while seated in the shell but not pressed, I feel I do bell the case enough as the bullets sits in the case. I'm not sure about the crimp I know when I used the bullet puller the diameter for the round is squished smaller, I think because there is a ring where the case stops.

These are the bullets I'm using,
