hey redhawk, the only thing i can tell you about the 4x versus the 2x, is that i have an encore pistol, 7mm-08 with the 4x, target aquisition(sp?) is strange, this is my first scoped pistol, and the salesman tried to persuede my to the 2x, i dont know if this is why but it has taken some getting used to, its like everthing you see in the scope moves around funny when you can see the same things around the outside of the scope. i don't know if that makes sense or not but thats how it seems to me with the long eye relief[&:]
