:I have been cruising this sight for the last couple of months. Purchased my first NEF rifle a few months ago.It's a BC ,first thing I did was put a Williams Foolproof sight on it and bead front sight .
Reduced groups by 1/2, On a good day I can make 4 out of 5 bullets touch at 50 yds.I use lee 340 gr. bulletts and 14 grs. Unique powder.
6-8 Inch groups at 200 yds. with the same load.
Also a pound of shot in the butt makes it balance much better for me.
