Hi guys.
i have had a problem with my scope at long distance, for years I have shot the English XX match at Bisley and used a 6.5 x 55 Swede with a good Japanese scope called an Optima, I hade it and it has worked and adjusted well for about ten years, it gave good elevation to over 1000 yds with a 20moa rail. this year I thought I would up my game and put a Sightron lll on my rifle same rail same rings, thinking I had a much better scope went to 900 yds raised the elevation from 600 to 900 yds and the scope locked out at 900, luckily it was dead on at that distance And I got a good score, but there was nothing left for 1000 so I had to hold over to get them in the 5. The question is why wasn't there enough adjustment on what I thought was a long distant scope also how would you experts out there rectify this problem.
Many Thanks.
