I have a VX3I 2.5-8 with a number one. I have to be honest, I'm a bit on the fence with it. Definitely not a reticle that should be one any sort of rifle you plan to shoot very far, IMO. I have moved it to my 20ga slug gun for next years deer hunt.
The #1 on the Leupolds are not as nice as that reticle. Much heavier middle post amd everything seems a bit crowded.
the number 1 leupold is maybe not that spread as the regular german 1 but it is working for fast use at short distance ...
