I have a 4-25 LRP S3. It's on a 21lb 338 edge. When I dial out for distance and shoot sometimes between 15 & 50 rounds I can't return to zero. It's like the price for the stop is moving under recoil. Have tighted to spec and beyond and still same thing. Anyone else seeing this issue. This is the 2nd one same issue.
