Last week I bought a new 6x24 PST. My rifle has a 40 moa NF base. With the turret turned bottomed out I am still 10 moa to high. I thought about going to a 20 moa which in theory should put me ten moa from bottoming out, but, with the turret at ten moa from the bottom, looking through the scope you can not see straight through it, by that I mean you can not see to the top edge of the scope (top edge to bottom edge). Looking in from the objective end the opening is oval shaped, and to get a perfectly round and clear view you need to have the turred at almost 24 moa from the bottom which would only give me 40 moa travel up. Has anyone else noticed this with their Viper PSTs? My Lupy VX 3 is 4 moa from the bottom and it is still perfect. I do realize the vortex reticle is etched onto the glass and the lupy has a tentioned wire. Anyone?
