It certainly looks like you are on the road to success.

I was looking at this photo and have a suggestion. It looks like your patch does not extend all the way to the bullet ojive. It should cover all the cylindrical shaft of the bullet and extend just very slightly onto the ojive. You don't want any lead in contact with the bore or rifling. All the lead slides down the barrel on a greased patch. Your bullet seating depth should be such that the patched bullet is snug against the leade, but without difficulty in closing the action.

I may be wrong in my view of this photo, but you might want to check on this.

The RCBS bullet really looks fine. I was thinking it would do well with my .450/.400 3.25" Farquharson, but the diameter at .406" is too large. I would have to size it down, adding another step to the process.
