Yesterday at my indoor range.
45LC Big Boy. Rear sight is Skinner -- receiver mount with a 3/4" Merit extender. Front sight is Lyman Globe using Lee Shaver inserts.
Here are results:
Both done at 25 yds, 45LC, 255 gr, copper plate FP
This first scan is 15 shots using the Lee Shaver with one of the small circle inserts. 2 1/4 group (Red target is 2" square)
The`next image was my last five shots using a slightly larger circle insert.
2.0" group (Red target is 5/8" inside a 1 5/8" circle)
I am quite happy with these results with eyes that are not young. Although better than they were two years ago, since I've had cataract surgery.
In the hands of a marksman, this gun would without question be considered a true tack-driver.
Next trip to the range, I am going to try the 3 middle inserts (lower row).
