From what I see on Nikon's website, the Prostaff 3-9x40 BDC is listed as a rimfire scope with a 50 yard parallax setting. http://www.nikonhunting.com/products...-_BDC_150/6725 They also list a Buckmasters 3-9x40 BDC and hopefully that's the one that comes with the Trophy Hunter package. http://www.nikonhunting.com/products...C_RETICLE/6421
