Well, time for a small update.
At the last test shooting, I discovered that I had to adjust the iron sigts even more than first calculated, due to clearance at the original setup. The bullet hit the target about 8cm to the left of the bullseye. After a quick calculation I decided to make a new washer/spacer. This time, 0,94mm thick.
I'm using the lathe for this work.
Some filing required to make the adjustment.
With the work done, I went to the shooting range and tested the adjustments.
Pretty happy with this. The third shot went up to the left. I guess the left is my fault, and the heigth is due to the heat.
Now I feel confident to hunt with this "old" drilling.
Cheers Joar
