Slowly over the past year I've been getting the primitive sights on rifle zeroed in. I've been using Graf's 2f powder. Monday I went out and got the windage where I wanted. The elevation was 7 inches or so low at 60 yards. When I got home and cleaned it up I filed .025 off the front sight. I think that's the 3rd time I've filed on it. Went back out Tuesday and for a change up I took GOEX 3f. Shooting again at 60 yards I was 6 inches high of the bull. Now I'm really talking to myself, I can't see anyway in the world that .025 off the sight is going to make that much difference. Humm, maybe I'll have to get on TOTW's site and order front sights. So today I went back out there with my Graf's 2f and shot. I was good for windage and about 2 inches low of the bull. Guess I'll file .015 off the front sight and stay with the Graf's.
