Bump dies

OK maybe I am a little dense but am trying to wrap my mind around making a bump or
nose sizing die.
Have read pretty much everything I can find and still am having trouble with it.
Does anyone have diagrams or prints of one they have made that they would share?
Maybe since reading doesn't do it a diagram might get the old brain cells to firing.
Thanks

I've never done it, but I've heard of people using a lube-sizer press.

Also, see Post #6 ...there is photos of using a Lyman lube-sizer die and a mod'd bolt in a arbor Press

I read a post on the CBA website that talked about swaging the nose portion of a bore rider bullet to get better accuracy.
Having never done anything like it was trying to find out as much as possible before trying to make something.
I guess I am grasping at straws to get better accuracy from my cast bullets.
As no one shoots cast at the range that I go to except me there is no one to ask if my groups are good enough or not.
So I am always trying to make them better and this seemed to be something to try.
Don't know if it will or not but worth a try.
Besides it gives me something to think about during this lockdown!
