I have the hornady headspace gauges.
They work good.
Not much to them though.
A must have IMO.
I would suggest returning the lube & pad, FCD.
and this goes super fast and really far!
While I am running through about 11K in 5.56 right now. I use 2 shots on the pan, cover it in 1 layer of brass, shake the pan for 10 seconds, dump in case feeder, done!
