I know of two pb gun manufacturers that send a test target with their guns...Anschutz and Cooper. I just wonder if any of the airgun makers do the same? I have two Anschutz rimfire rifles and they came with a test target.
Our Fearless Leader made a video @ RAW and showed the test tunnel .Some of the Eastern European guns do - Taipan and Airmaks, I'm pretty sure. Maybe also Kalibrgun and Airgun Technologies.
I have heard that RAW tests all of their guns for accuracy before shipping, but I have never seen a target from them.
