I shot about 100 rounds through my .308 SPS-V which has a Millet LRS on it. It wasn't the first time shooting it but it was the first time that I shot that many rounds. I noticed after about 40 shots that my scope was sliding forward in the rings. The rings on it are made by Millet and came with the scope. They are the "tactical" looking type with 6 screws on top. I checked the screws on both rings and all 6 on each were tight. I do use caution not to over tighten them, but they were pretty snug none the less. It's not sliding on the base or anything and it's not sliding back like I would expect, it's just sliding forward after shooting. Is it the rings? Because I don't think I should tighten them any more then they are. Thanks
