Sure, any of the reamer makers that make the reamer, have head space gauges. You only need a go gage a piece of scotch tape over the end of the gage will give you the NO GO.
Go to the home page on this site and click on the reamer or just look for PT&G ad. That is the only one that advertises here. Or do a web search for J&G or Manson, I can't remember the other dozen or so, right off the moment.
