While I've never experienced poi shift from my Sightrons, I do experience range shifts. This is mostly due to available light vs ambient temp. I have yet to let my scope bake in the sun, but also have the necessary equipment to keep it shaded during a match so don't see the need.
What scopes have less or more shift as a brand, and model than anyone would like to add here?
