By George, you ARE older. I feel better now.
I haven't had that many Encore/Contender frames but barrels I've had (quite a few sold over the years) probably run 40 or 50. My taste in scopes has also changed over the years. I used to be quite satisfied with Tasco and Bushnell scopes. My tastes now run to Leupold VX-III, Leupold Mark 4 (especially illuminated), Nightforce and Zeiss. Not only is it less expensive to switch scopes between barrels, but barrels and scopes take up less room in the gun safe. In addition, there really isn't much downside since the QD rings hold them securely and if you record scope settings on target turrets, you can easily get scopes back to zero.
But, each to his own.
