Sure, very easy, if you have an inertia puller. That being the kind that looks like a hammer, putting the shell in one side with the screwable cap, whack it on the floor a couple times till said bullet comes free. Then carefully dump out the bullet and powder, rebell the shell, recharge the shell, and put in a proper sized boolit. With practice, one can tap that bullet out of the shell right up to the base and pull the bullet off without powder spillage, but it takes practice. Clear as mud, yes?
