I just had a Burris 2-7X compact go bad on me, it has a shifting point of aim, and the sight picture goes from crystal clear to blurry. The scope had not seen a lot of use, so im not impressed to say the least, now im going to see how good that "forever" warranty is, and what they do about it. What size Talley's did you get? I shoot a 6.5X55 in a Rem 700 classic and it one of my favorite cartridges, accurate, low recoil and report, and it plain kills stuff quick. What rifle twist rate are you using, hopefully its the 1 in 8"
