I have an Aztec 5.5 × 25 x 50 that I have lost total trust in. I really like the glass and reticle. Maybe it is me or it is my HM1000X. 25 raw. I'm just a regular old guy trying to make this rifle shoot the best it and I can. This is what is going on . Sight it in today, tomorrow the rifle will shoot 4 -5" high or low depending on where I adjusted the scope the day before. If I shoot an extended while the scope will slowly move in elevation the direction it was adjusted to. This scope is almost a year old. Get a new scope? Throw the gun in the dumpster. Buy new gun and scope. Any and all suggestions welcomed. Thanks Barry
