Finally got to sight in an older (made in USA) weaver T 16. I started at 40 meters, and for best clarity the objective was set at 47. The number on the movable being 7; number on the stationary part being closest to 4. I thought this was very close to the actual yards I was shooting at until I moved the target back to 60 meters. Instead of going to a higher number for more distance, the best scope picture had the objective lens set at 45!
When I got to 77 meters, the best clarity was with the objective set at 42.
At 100 meters, the objective setting was 39. I experimented with trying to set the objective at both extremes of its travel, but all I got was very blurry results. The elevation and windage knobs worked very smoothly and were checked for repeatability. From chickens to rams I used 8.5 minutes of elevation with Federal 711B Gold Medal ammo, same as my other rifle with a Leoupold scope.
My question is- what do the numbers on the objective lens represent, and why are they decreasing when the range is increasing? Anybody got an owners manual for this T-16? It also has a dot reticle(1/2") and a Premier Reticle sticker. I bought it used, with no papers.
Thanks, Jim
