We have developed two tools for our 50 BMG customers (shown above). Measure overall length accurately with our new .50 caliber bullet comparator. The Sinclair Bump Gauge for the .50 BMG allows you to accurately measure cases at the shoulder so you can adjust your dies for proper sizing. Both the bullet comparator and bump gauge attach directly to dial or digital calipers. We recommend the use of 8" calipers with both tools.

A good idea, but not practical(17/10/2014)
Quality construction and finish.
Works fine as a shoulder bump gauge, BUT the interior diameter is only .560, so will not fit most .50BMG brass that has been fired out of a standard chamber without first neck sizing the brass down to under that. Might be good to use if you have a tight-neck match chamber.
I bought it mainly for its advertised secondary function as a ogive gage. This it fails, unless you are maybe doing .510 dangerous game type bullets. The tip of a standard .50 BMG ball bullet hits the inside top of the gage well before the ogive is reached. So of no use checking .50BMG seating depth when reloading.
