I used them once. I had a older Vari X II I believe it was. I had just sighted it in the day before. I took a deer opening day @ 225 yds but the bullet was nowhere close to where I held it shooting from a rest. I went to the 100 yd range the club had set up. I was lucky to get it on the paper. I resighted it and the next day I missed a easy shot. The scope went back to Leupold and in no time I got it back. They replaced the P.O.I. adjustment mechanism. It's been several years back, I remounted the repaired scope on the same rifle. I hate to admit this but I haven't taken that rifle or scope back out to sight it in. I'm sure they fixed it Leupold makes a good product. That is why unless I'm close to the house I always take more than one rifle with me, because you just never know.
