While I'm not familiar with the aimpro reticule, I do have a compact 1 x 4 Busnell Banner with the circle 'X' reticule on my 30-30 Handi. It is a neat idea for a quick shot in the woods, but I'd just as soon just have a normal duplex in it. I'm putting a VERY compact little Simmons 4 x on my 45 CC as soon as I get back to Michigan. For some unknown reason that will never be repeated, I'm in Texas at the moment and the CC is back in Michigan. There's been several times that I wished I had that little gun with me. 44 Man.
