OK got to the range again today, finally, with the 38-55 with mixed results.
Still shooting BP and the cast bullets, and the newly modified rear mount (again). Well it's shooting about 12" high at 50yds at the lowest setting. I guess I need to raise the front somehow.
So just for kicks, I pick out some far away targets. One was a piggie about 18" long at 200yds. Nailed it 4 out of five times. The bad part, was the rear mount was still at the LOWEST setting.
The good part, is this thing will probably lob bullets WAY out there at the top setting.
And so it continues.
