I don't trust Leupold as a general rule for dialing, but I have a 20 year old 4.5-14x50 LR that has been great. It's been on a lot of rifles and sits now on a 338 Edge. I don't use it much, but it's had 1-2000 rounds through it dialing and hasn't gone back to be fixed yet. I think in general, the older ones are better than the new.
