After some sight adjustments I still had some rounds left, so I decided to do some rapid shooting. I don't know why the bolt locked back after the first round. Could be the ammo (Tulammo), but it could also be the magazine hanging up slightly.
I'm trying not to hit the steel targets on the range, as they would get pierced.
The range was safe, and there is sufficient backstop in the directions I'm shooting.
