Yesterday I tested the new self-made rear sight / safety replacement.
The sight allows to make the fast distance correction adjustment.
Tested on Rossi 92 .454 Casull, 20" barrel, with Magtech FMJ (see photo) and self-casted bullets (wheel weights, Lee 452-255-RF, 18 gr of Sunar-410 powder, speed is around 510 m/s, distance 25 m).
