How to measure for and set up FLR shoulder bump?

I just want to add , when you start to size the fully expanded brass , the brass will get longer , before it starts to get shorter , this is normal . just keep slowly turning the die down little bits at a time . I like the redding competition shellholder sets . they make bumping shoulders easy .

Jeff Brozovich had a great vid on setting up his dies. It shows how to remove the firing pin, size a case and try it in the rifle. Keep screwing the die down until the bolt will go down with very little resistance. It's a great vid and is how I set my dies up. I use the Hornady comparator and Whidden bump gauges to measure and record the measurement for reference.. Even though he uses the competition shell holder kit, this can all be done with standard dies and shell holders.

Alex Wheeler doesn't use comp shell holders . here is his video collection . second down on the right is brass sizing .

the redding competition shell holders are a great help. different brass will sometimes have a different spring back and the next thickness shell holder might give the desired shoulder bump without moving your sizing die.

I agree, I have not found one negative aspect, using the comp shell holders. That's the main reason I only seat with my CO-AX and set up a RockChucker for sizing.
