My custom 3-9 EFR has very fine crosshairs and centre dot, no other bars or posts at all. It was one of a batch made by the Leupold Custom Shop. I like dots, as the eye tends to centre them automatically within circular targets. However, in the woods and on gloomy days the dot can be hard to spot, especially if the kill zone is painted black!
At the previous year's Newark show, I picked up a second hand Leupold MR/T with illuminated TMR (I think) reticle. This has a rather bolder centre dot, no wires or bars at all and just a large circle outboard of the dot. I've had mixed results with this little scope and the fixed parallax has necessitated setting on about 6x to keep as much of the field as possible in sharp focus.
Only another few months to the next show (Stoneleigh this time), when I'll be on the look out for another HFT scope.
