Hi all,
Aspects of this topic have begun to come up in OSAC and ASB. Consideration might be warranted on what such a process actually can be categorized as, as a calibration or as a performance check. If the process is not conducted by a lab accredited for that type of calibration (which most forensic firearms labs are not) you may have trouble representing that as calibration when it comes to accreditation requirements. It does seem like a valid and appropriate way to check that the instrument is providing the expected results as a periodic performance check.
Again, this is just some conversation that has come up in relation to documents that have still not been finalized or published, so things could change. There are others who are as familiar, or more so, than I am. If anyone else wants to chime in and join me in being a wet blanket you can.
