The only time I remember having a problem is when I had a scope mounted at a gun shop. I bought everything there so I thought I’d let them set it up, Leupold scope & all.
I go to the range & the gun wouldn’t stay predictable. I checked it out & saw the scope was loose in the rings, no tool with to tighten. I abandoned ship, went home, redid everything myself. I think I was talking to him to much while he worked.
Before & after I’ve always just done it myself, nothing difficult. At times I’ll include a ballpark ‘boresight’ by aligning the crosshairs & bore on a clear targeting point. The real key is to get on paper at 25 yards, adjust on single shots until close. After that, extend the range & fine tune.
