....my other question is the outdoor range is "for sight-in only". Meaning bore sighting, or actual sighting in the firearm and what is the caliber size limit?
So theoretically, you can use the range any time there open, and if anyone says anything, you just tell them that I'm "sighting-in" the rifle.
NE Bull can chime in if my memory has failed me more than usual. In our discussions with G&P, the term "Sight-in Range" was used to describe informal, unsupervised, ranges that would be developed at existing G&P locations, such as WMA's or SRA's. We brought it to G&P's attention that there were large numbers of big game permits sold in the state each year, but there were few publicly accessible places available for those permit holders to sight in their rifles. That discussion was where the term "Sight-in Range" originated.
In our discussions with G&P re: range design, they were planning that a typical sight-in range would be set up for both rifle and pistol use. There was never any discussion about limiting the use of "Sight-in Ranges" to just the sighting in of hunting rifles. Our understanding has been that the sight-in ranges could be used for most anything that any informal, unsupervised range could be used for, i.e. plinking, testing handloads, informal target shooting, and/or the sighting in of deer rifles.
I don't recall that we were ever involved in any discussion of caliber limitations. I believe G&P was originally planning on including some hanging steel for targets, along with more conventional target backers. JMO, but any caliber limitations for a given sight-in range would probably depend on the location of the range itself, and on G&P's final design for the target area at each range. G&P will probably develop, and post any special requirements at each sight-in range.
