I put on the second scope and zeroed in at 50 yards again. I then tried it at 100 and the slugs were about a foot high. I had a local firearms expert check it out atthe range with me and he had no explanation for it. I thought it had to be the scope so I tried a second one and it still did it. I have used the lightfields for 3-4 seasons with excellent results before this. In factthey worked perfectly at the range before the season started. Idon't have a clue why this is happening.
