This is five shots at fifty yards. Ammunition was '61 South African.

Another five shots, this time at 100 yards - same ammo. I think if I used a solid black target I could have avoided some of the stringing. Overall I'm very impressed.

I did shoot it at 200 as well, but didn't get any groups worth posting. All of the shots were low (despite the rear sight being set at 200) and left. I have no idea what role the wind played, if any. I need to go back and take my time at that distance.
... it's definitely going to be hard to part with this one.
