Sighted in the 71 this week. It was high at 50 yds with 200g silvertips, but luckily it was dead on with 250g Woodleighs. Looked at adjusting the vertical but could not turn the Up/Dn knob. I can push the sight down with finger pressure, which allows the knob to float around freely. I left off the finger pressure and the up/dn knob is put under pressure. But either way it will not turn. I have not forced it in either position. How does this thing adjust vertically?
